This movie had me, then lost me (spoilers!)
I liked how it showed the reality of gambling as a sickness, and how they never won anything. I believe it was a coward move to give some lukewarm results at the end. It could've ended with the cold and hard reality that it was showing the first 3 quarters so well: the grinding never stops, no matter what you tell yourself, you keep losing and digging further into the hole. The knife wound could've gone somewhere, it went nowhere!
So 3/4 european movie (cold, real, and hard, couldn't care less about your feelings), last 1/4 american "I don't feel so bad now" movie. What a shame.
