I thought it was great. Fairly low key, but clever and genuinely funny with an actual plot! Something most comedies just don't bother with now. It had lots of little touches for movie fans (I still love it when Jones reveals what film he stole!).
It's more honest than Judd Apatow's stuff which was getting lazy, and don't get me started on Hangover 2. I saw this a week or two after that insulting pile of... *sigh* let's just say I was a bit disappointed with Hangover 2. Long time since I felt like a film was laughing at me for watching it, rather than the other way around!
As with Ted, Horrible Bosses just felt fresh and old fashioned at the same time. Bring on more!
