Saw Trainwreck this past weekend - I'm usually not a rom-com guy - I find them to be very formulaic and stale. While the usual tropes and formulas were detectable in this movie, the movie itself was pretty damn funny. John Cena was hilarious. The jokes were really great and the supporting cast was phenomenal (fuckin' Colin Quinn was stupendous in it). While this isn't a case of the whole is greater than the sum of it's parts (due to the overall predictable formula), the individual performances were cohesive to make it worth watching and enjoying.
I've liked Amy Schumer for a while (I know she's kind of blowing up, but I remember when she would make bit appearances on sketch comedy shows or stand up bits and I thought she was funny) and she really killed it. The ending felt a little rushed, which isn't necessarily a bad thing as it was a lot of fun to watch her be a fucking mess for a good hour and a half. Bill Hader played it relatively straight.
One of the castings which I was most excited about was Mike Birbiglia! He's been one of my favorite comedians for at least the past 7 years - I saw his Sleepwalk with Me show in NYC when he was performing - and, although he had a small part, it was awesome to see him in there. Definitely worth a full price admission.
