BS Hype Factor
I just watched the movie. Lots of stuff was "off the mark" but I guess it's a matter of making the movie interesting. I think the movie will attract lots of people to the casinos, thinking it's all such "easy money". Besides the little details that have been pointed out, such as the room view that is not from the depicted casino, etc., there is the obvious.
The movie makes it look like there's no such thing as losing in a good count, which is ridiculous. Those of us that play 25-50 hours of blackjack a week know darn well that huge losing streaks and horrific losses can occur even if the count is good. Of course the movie can't depict that because it would take away from the glitz factor of the movie. The fluctuation factor and the cold, hard fact that with an insufficient bankroll, lack of practical application, lack of experience that lends to having common sense and money management skills, etc....you can be the best card counter going and will still likely fail in the long run.
The other things, which were pointed out such as the smartest kid at MIT that stuffs loads of cash in his dorm and has no clue what a safety deposit box in a bank is....I mean...come ON! How many people are THAT stupid???? I thought the movie was still entertaining regardless.
