Writer/director Cameron Crowe presents us with an attractive and talented but messy and compromised hero in “Aloha,” and asks us to root for him. The problem is that the film itself is attractive, talent-filled, messy, and compromised, and harder to root for than the hero of the story.

That hero is Brian Gilcrest (Bradley Cooper), once an 11-year-old who loved the sky so much he wanted to identify everything in it. In a quick narrated recap that opens the film we learn that after he grew up things went well for him (in the military) and then not so well, and then badly. While working for a private contractor in Kabul, he was badly injured, and apparently not in the way that gets you a Purple Heart.

Brian arrives in Hawaii and needs to prove himself. His former employer, Carson Welch (Bill Murray) is one of the wealthiest men in the world, presiding over a telecommunications empire. He and the Air Force are working together on a big project that involves the development of land on the island that was a burial ground for the indigenous people. The Air Force assigns a “fast burner” named Sergeant Ng (Emma Stone) to work with get the cooperation of the King of the native population to build on that property, and to show that by performing a blessing ceremony. The King is played by real-life King Dennis “Bumpy” Kanahele, and he is one of the few from Brian’s past who seems to like him much. Welch does not. The Air Force General (Alec Baldwin, volcanically angry) does not. Then there is Brian’s ex-girlfriend, Tracy (Rachel McAdams), now married to an Air Force pilot and the mother of two children.

It totally goes off the rails several times, with a plot that would daunt a Bond villain thwarted by a completely ridiculous hacking scene, plus a last-minute redemptive reconciliation that is so far off the mark of any known human response the characters would be just as likely to sprout feathers and levitate off the ground. While the Hawaiian natives and their struggle against what they see as American imperialism and colonialism are sympathetically portrayed, it is still a story that is about white people and their problems. And the casting of Emma Stone as bi-racial is insensitive at best.

But like its hero and its writer/director, it won me back with the crackle of its dialog and charm of its poetry, even in the hacking scene, and especially in a statement of romantic intent that is one of the best I’ve seen in many months. It is also very funny, with a wonderfully expressive performance from Krasinski as the taciturn Woody, and thoughtful work from Cooper, who keeps getting better at finding moments of surprising insight and nuance with every performance.

Parents should know that this film includes strong language, sexual references and non-explicit situation, paternity issue, references to war-related violence and injuries and to weapons of mass destruction, references to imperialism and colonialism, and alcohol.

Family discussion: Why did Ng talk so much about being one-quarter Hawaiian? Why was the King the only person from Brian’s past who seemed to like him? What happens when billionaires make decisions that used to be made by government?
