terrible lack of blood ..
just saying.. it would make the whole movie much more believable if getting clean shots to the head and nose produced blood pouring out of your nose..
look at the real MMA fights..if you get hit on your nose, you bleed, if you get hit on the area around your eyes-you bleed..
kevin james character got hit sooo many times on his nose yet nothing.. its like he can withstand clean straight shots into the head without KO..
this is the biggest flaw of the movie.. they shouldn't have him take soo many shots in the head, or if he does get them, he should be looking like a car wreck by the end of the day..yet he has no bruises, no nothing.. accept for that leg gash in the beggining..
