No surprises here, but it is a pleasant date-movie, a romance that tries hard to transcend its gimmick and just about succeeds. Let’s get the gimmick out of the way first – guy has girl (architect Bob — David Duchovney — married to beautiful Elizabeth — zookeeper Joely Richardson). Then guy loses girl in a car accident, guy meets new girl named Grace (Minnie Driver) who doesn’t want to tell him that she had a heart transplant, guy finds out that the heart came from his late wife, and everyone gets over it and gets on with living happily ever after.

I know, I know, it is a very creaky premise. At least it isn’t one of those movies that drags out the telling part and then just as she is about to spill the beans he finds out anyway and it takes another half hour to straighten it all out. And at least there is no maudlin “Chicken Soup for the Soul”-type stuff about how this is the gift his late wife brought to him or anything like that. Grace tells Bob as soon as she finds out and it does not take him too long to figure out that he loves her anyway, and if it just happens that the big clinch happens in Italy, where he was always trying to take Elizabeth, we won’t make too big a thing of it.

We know where it is all going from the first five minutes. So we can sit back and enjoy the ride, in the capable hands of director/co-star/co- scriptwriter Bonnie Hunt. Hunt, a terrific character actress (Renée Zellweger’s sister in “Jerry Maguire” and Tom Hanks’ wife in “The Green Mile”) lets the couple’s friends and family add a lot of life and depth to the story. They give Bob and Grace more personality and interest, sort of character by association.

Grace lives with her grandfather (Carroll O’Connor), owner of an Irish-Italian restaurant that is home to a community so adorable and loving that they could be birds and cherubs perching on the finger of an animated Disney heroine. Her friend Megan (director Hunt) is living in happy domestic chaos with her husband (James Belushi) and four children. Bob’s friend Charlie (David Alan Grier) is there to fix him up with Ms. Wrong, so that he can have a reason to go to Grace’s grandfather’s restaurant and leave behind the 21st century equivalent of a glass slipper – his cell phone.

Everyone has to cope with the risks of letting others see us clearly. It is not just major secrets like heart transplants that people are afraid to share with others. Families who see this movie should talk about how people decide how much of themselves to share, about how people cope with loss that seems devastatingly overwhelming, and about Grace’s grandfather’s comment that “It is the character that’s the strongest that God gives the most challenges to.” Before Grace goes out with Bob for the first time, Megan advises her not to shave her legs, as insurance against “going too far.” This is a rare movie in which the couple does not go to bed together almost immediately, partly because of Grace’s sensitivity about her scar, and possibly also because Bob needs to take things slowly, too. Some families will want to talk about how couples make decisions about the risks of physical intimacy as well as emotional. And families should also talk about the loving way the people in this movie care for each other and enjoy each other.

Parents should know that though the movie is rated PG, there are a few strong words, including some used by children, and some mild sexual references.

Families who enjoy this movie will also like “Sleepless in Seattle.”

Hong Kong action star Jet Li (“Lethal Weapon 4”) and R&B artist Aliyah are a hip-hop Romeo and Juliet in this tired tale of rival gangters. Fans of martial arts will do well to wait for it to come out on video, so they can fast-forward through all the meaningless exposition and endless shots of people giving mean and meaningful looks at each other and get to the good stuff.

Delroy Lindo is Isaak O’Day, a gangster who dreams of going legit, “making deals in country clubs instad of pool halls.” He loves his children, Colin (D.B. Woodside) and Trish (Aliyah) deeply and wants to protect them. But Colin wants to “be a man,” and for him that means taking matters into his own hands.

Kai Sung (Russell Wong) is the leader of the rival gang. Like O’Day, he has a son who wants to be a player. He and O’Day are trying to get the deeds to the shoreline property in their districts, to turn it over to a sleezy developer who is competing for a football franchise. We know he’s sleezy because he keeps saying fake profound things in an arrogant way, like,” golf is a game of finesse, not power, much like life,” and “If I say there is caviar on the mountain, you just bring some crackers.”

When Sung’s son is killed, his brother Han (Jet Li) breaks out of a Hong Kong prison to come to the US to avenge his death. He meets Trish, and they find that they have more in common with each other than with their sides in the fight.

There are some nice fight scenes, though it seems an insult to Jet Li’s extraordinary talent to trick them up with computer graphics. If we want to see people suspended in the air while they kick each other, we can rent “The Matrix.” Little flashes of x-ray shots of bones being crunched are an interesting touch. When you’re fast-forwarding the video, be sure to stop and see it.

Parents should know that the movie has very strong violence, some girl/girl kissing, drug use, and that it is really dumb. (I especially love the ending, with Han and Trish wandering out of the house with all the dead people, the police completely ignoring them.) Families who see the movie may want to talk about racism and the way that children prove their independence, or maybe just how such bad movies get made.

This movie should be called “Smart and Smarter.” In addition to the thrilling story, masterful performances, and impeccable technical authenticity, it is a heartening story of the triumph of smart guys with slide rules, a relief in this era of movies about characters who triumph by being dumb. Two-time Oscar winner Tom Hanks plays real-life astronaut- hero Jim Lovell in this true story of the mission to the moon that almost left three astronauts stranded in space, when an oxygen tank exploded. Even though we know it turned out all right, even though the technical material is dense and the action is confined to a space smaller than an elevator, the tension is breathtaking, as the astronauts and the mission control team in Houston try to think their way back home. Everything from duct tape to the cover of the flight manual to one of the astronaut’s socks is used in this pre-McGuyver story, where mission control asks simply, “What’s good on that ship?” and builds from there.

Because of the technical material and intensity of the story, it is a good idea to prepare younger kids beforehand by telling them what the movie is about, and you may want to reassure them, since it is a true story, that the astronauts did come home all right.

Talk to older kids about the way that Mission Control solves the problems happening thousands of miles away, by re-creating the conditions inside the spaceship. Point out how the adults handle the strain, sometimes losing their tempers or blaming one another (or trying to escape blame), but mostly working very well together. Lovell and Ken Mattingly (Gary Sinese) were presented with a very tough problem when exposure to the measles led Mission Control to pull Mattingly from the mission. Lovell tries to insist that Mattingly go along, but ultimately realizes that the good of the mission has to override his feelings of loyalty. Kids may have their own ideas about how this should have been handled.

The legendary “Failure is not an option,” said by Gene Kranz, head of Mission Control, when most people were certain the astronauts would never make it back, is worth discussing. So are the changes since you were your children’s age. Note that everyone in Mission Control is a white male (and they all smoke all the time). They are amazed that a computer is small enough to fit into one room. And you may have to explain why adults who watch the movie laugh when the engineers take out their slide rules — for kids today, they are more exotic than an abacus.
