I thought Warrior was a good movie, but I had such a hard time suspending my disbelief at the whole tournament business.
*SPOILER ALERT*
What kind of world-class tournament (supposedly only letting in the absolutely best of the best fighters) lets in a completely unknown fighter without a single MMA fight in his record and a washed-up UFC fighter who hadn't fought in years? The whole Koba business was so stupid. Why didn't they just write it so Tommy fought him instead of Brendan? It's already hard enough to believe Brendan would beat him in such a state of exhaustion, but to then beat Tommy? The movie didn't have to go so fucking Hollywood to tell such a great story. I feel this movie could have been in the upper echelon of cinema if they had just toned down that whole shit. Alas, they fucked it up and quite frankly insulted MMA as a sport.
EDIT: The Hobbit fucking rules. I saw it yesterday and it brought me back to my childhood with a vengeance.
