I say it all the time, I come from the sports world, so quite often I find the portrayal of sports in movies beyond laughable. Movies can get 'stupid' because the producers often assume the audience is stupid – at least when it comes to that particular arena.
Gotta turn that nonsense into a script that works. You will see that in every movie about competitive worlds doesn't matter if it's sport, war, politics, whatever.
Nah it was a great movie, it was just stupid when it came to the technicalities of poker.
