"I haven't been that sad since they killed Josh Charles on The Good Wife." I'm pretty sure I was the only one in my showing that laughed at that line.
Loses just a smidge of steam in the back half but damn if the first 45 minutes or so aren't jam-packed with laughs. The Bin Laden song killed me, and Will Arnett popping up to poke fun at Harvey Levin/TMZ was terrific. Also, Bill Hader's roadie absolutely has a Letterboxd account.
