I found this movie to be very gripping, but like others have said it requires some connection with the main character. For me it was there and I thoroughly enjoyed it (as did my wife who insisted we watch it again a week later).
I really enjoyed the brief table dialogues, one of my favorite succinct quotes being something along the lines of:
Walhberg: (Pushes a 10k stack onto the blackjack table) Dealer: That is $10,000 dollars, are you sure... Walhberg: Are you a financial adviser or a dealer?
Walhbergs character is pretty unique, and borders on unbelievable, but it very consistent and represents very real emotions.
