I don't think this movie was suppose to come off as hilarious, but I found myself laughing quite a bit. I don't know if it was the racial slurs or the way Clint Eastwood said "pussy", I loved it all.
Overall, the movie is quite good. The plot is subtle and slow, but the character interaction is superb. There's even a song at the end sung by Clint Eastwood to top of the movie! Listen to it, it's ridiculous.
Anyway, I recommend this movie to everyone.
