The road trip movie is a familiar genre: A pair or a group — who hate each other and learn to love one another, or love each other and learn to hate one another — travel through the country, learning about themselves and the world along the way.But how often do you see such a flick where the trippers are an anorexic, an obsessive-compulsive and a man suffering from Tourette’s syndrome? That’s ready-made comedy, but “Vincent Wants to Sea” doesn’t take the easy path to redemption. This German film is quirky, but doesn’t rely just on the foibles of its motley crew to provoke laughs — or tears.

The film opens on a funeral, with a clergyman intoning on the meaning of everlasting life. A man in the front pew looks uncomfortable. Is he about to cry? Throw up? Laugh?
