I love Amy Schumer. I think she's incredibly funny and self-deprecating, and she doesn't seem to mind getting down in the gutter if the joke requires it.
Bill Hader joins her here as her love interest, and they seem perfectly suited to play off one another. Brie Larson, Jon Glaser, and Colin Quinn all do a good job, but the one who steals the show is the always excellent Tilda Swinton, here playing a magazine editor so morally corrupt she is outrageously and funnily good.
The Bottom Line: Trainwreck is not a great comedy in the classical sense, but if you're just looking for a couple hours of mindless laughs, then look no further.
