Trainwreck is Schumer's first starring movie role; she also wrote the script. And while the picture is occasionally very funny -- because when she lets loose, Schumer does have a fantastic, loosey-goosey wiliness — it also feels carefully constructed to make its points, chief among them that men can get away with all kinds of bad or crazy behavior that women can't.
Schumer plays a hard-drinking magazine journalist who is determinedly uncommitted and noncommittal; her parents' marital breakup, years before, led her to doubt whether monogamy is even possible. Then she meets a sweet, successful, super-nerdy orthopedic surgeon, Bill Hader's Aaron, who's unlike anyone she's ever known. She falls for him, irrationally and almost immediately.
Schumer may be the writer and star, but Judd Apatow is the director, and in the end, you can't escape the feeling that somehow Schumer's vision has been wrestled into the template that nearly all of his movies, even the best ones, follow: one in which the comforts of conventional partnerships and family life are what we should all aspire to. Apatow and Schumer probably believe they've made a feminist picture, but this is a conventional movie dressed as a progressive one.
