From the reviews, you can probably tell this movie is hit or miss for some people. I feel like the people who didn't like this movie, had zero clue what the movie was about. This is a movie about gambling and a guy who's trying to get himself out of huge debt. That isn't pretty, even in the movies.
Sandler's acting was great. He does a great portraying his character, even if he's swearing the whole movie.
This movie isn't for the light of heart. It's a dark movie without light at the end of the tunnel. Proceed with caution if you aren't into that.
