I just saw Old School and enjoyed it (not great, but worth a few laughs). I've missed Will Farrell from SNL since he left, but I think the real star was Vince Vaughn's character. It's pretty much the same creepy asshole from his post-Swingers film Made, which that itself was a stronger version of the Swingers asshole.
Speaking of creepy asshole characters, I have to say The Office (now on BBC America) raises it to an artform. Every line they give David and Finchy are cringe-worthy and hilarious. It took a couple episodes for me to get into the show, but now I can't miss it. It feels a lot like the unscripted comedies like Best in Show, Spinal Tap, and Waiting for Guffman.
