“Made of Honor” has gloss and bounce and some of the core elements of a mainstream chick flick/date movie. Sexiest Man Alive runner-up in lead role? Yep, Dr. McDreamy himself. I’ve been a Patrick Dempsey fan since he did the African anteater dance in Can’t Buy Me Love. Does he get his comeuppance? In a romantic comedy, it’s always a good thing if someone gets a comeuppance. Yes, that’s here, too. And much of the movie concerns wedding plans, usually a reliable plot line. Consistent with wedding custom, it has something old (boy meets girl, boy loses girl…), something new (we’ll get back to that later), something borrowed (the plots of “The Wedding Planner,” “My Best Friend’s Wedding,” half a dozen “Friends” episodes featuring Ross and Rachel, etc. etc.), and something blue (some of the humor pushes the PG-13 limits to the edge). But it leaves out a few other essentials.

Ten years after college, Tom still sleeps with as many beautiful women as possible, not-so-gently informing each of them that he has “rules” — no one gets him two nights in a row, no one gets to visit his apartment, no one meets his family, etc. etc. The one constant in his life is his weekly time with college pal Hannah (Michelle Monaghan of “Gone Baby Gone”), his best friend. When she returns from a six-week business trip to Scotland engaged to a bonny broth of a Mr. Right (think the Laird of Right), Tom suddenly realizes that it is Hannah he truly loves. She wants him to be her Maid of Honor and he accepts because he thinks it will help him stop the wedding and prove to Hannah that he’s the one.

Despite Dempsey’s charm and charisma, the character he plays is hard to root for, more a male fantasy than a female one. The screenwriters and director seem mystified by women and sometimes even downright misogynistic, never a good thing in a chick flick. Women all take one look at tom and sigh, endlessly willing to do anything from write their phone numbers on Starbucks coffee cups to jump into (or back into) bed with him, one even yelling “Service me!” Three different times, the movie makes fun of an elderly lady who mistakes a sex toy (glow in the dark!) for a necklace. Not funny even once. Tom is immature and self-centered. He has no job, no interest in anything but hanging out with his basketball-playing buddies, having sex with many different girls, and his weekly date with Hannah, which is primarily about making him feel good. Even when she gets engaged, it never occurs to him to think about what would make her happy. The movie avoids the usual formula of making the designated loser in the marriage sweepstakes obviously wrong for Hannah but forgets to substitute some other reason to root for Tom. As happens too often these days, the movie relies on vulgarity instead of wit, insults instead of banter, and recycled ideas instead of anything fresh. It is so sloppy it does not know the difference between a blog and a post or between a museum conservator and a curator and has homophobic (literally) locker-room humor that would be considered childish by 14-year-olds. When the highlights of the movie are seeing Dempsey juggle china and a wedding video featuring Elizabeth Hasselbeck, you know the script is a couple of bridesmaids short of a wedding party.
