As much as I like Judd Apatow and his comedies (from “Knocked Up” to “This is 40”), I didn’t fully appreciate his latest effort. “Trainwreck” is frustratingly uneven and drags at 125 minutes . Luckily, the movie never runs on sitcom empty. How could it, with a terrific cast, led by Amy Schumer as a highly sexual woman who likes to drink and party but isn’t looking for a serious relationship (one of her sex partners is WWE’s John Cena in a hilarious role). Then Amy is assigned by her boss (Tilda Swinton) to interview a hotshot sports doctor (Bill Hader) who turns out to be a really nice guy. Will there be an attraction? Naturally. If you’re familiar with Apatow’s style, you’ll notice how he cleverly integrates real life issues into his comedic narratives. And he’s found the perfect actress to carry his movie through, even though the story runs out of steam at some point. Still,”Trainwreck” builds up a rooting interest in its characters and slaps a goofy smile on your face. It’s far from being my favorite Apatow comedy, but it’s entertaining enough and definitely worth the price of admission.
