If you hate Sandler and someone tries to get you to see the movie, do it. You might still hate Sandler, but you'll like the movie.

Okay, I plagiarized the summary from jjs402's comment. But it pretty much summarizes how I felt about the movie.
I hit a late (late, late, late) showing Friday night. I'm DEFINITELY not a Sandler fan. I find him, at best, dreadfully repetitious.
I liked "Little Nicky", but mostly because it avoided most of Sandler's signature histrionics. But just about everything else he's in, I've avoided like the plague.
So, with a bit of trepidation, I caught the flick.
And I liked it.
I still can't stand Sandler, but I liked "50".
Heck, one of the best parts was Drew giving a beatdown, Sammy Sosa-Style, to a certain obnoxious comic.
