I would have never got it.
It's a mix-mash of a movie.
You may still enjoy it, but it's almost like 3 movies in 1:
1. The comedy - Shallow Hal
2. The tasteless comedy - complete with Rhino and Water Buffalo jokes, breaking chairs, and other insults
3. The social commentary and heartwarming feel-good romance.
Mostly, it's #'s 1 & 2 that don't jive with each other. This isn't a 'straight' comedy, because it's marred with insensitive jokes that COULD have been used just to enhance the feelings at the beginning, but even at the end of the movie they're still throwing them around. It's just a mess of a movie. They add some feel-good commentary, but *other characters* don't act consistently, and when they do stir up more responsible feelings, they let them die under the next rhino joke.
Pathetic. If I want low-brow humor, I'll watch a Kevin Smith flick and love it. This was a stinker.
