You can explain away everything but this
I liked this movie, good action flick, unique plot twists, plenty of real MMA/UFC characters, great acting, sleazy sleazeballs, ups and downs, great nuevo flamenco-style guitar soundtrack, you name it. The plot holes already inveiled can be overlooked and explained away, except for one I have yet to see mentioned:
No way would a true martial artist dream up the handicap scheme. And no way would a martial artist with even the tiniest bit of honor step into the ring with anyone who was not able to fight to his full potential due to an artificial handicap. There is no honor in winning under such circumstances.
Ah, well, I guess the writers needed some extra plot twist to put it all together. I still liked the movie, I just thought that was in glaring opposition to the theme of martial honor that this movie strove so hard to present.
ADDED: OK, for those who missed my follow-up, I concede the handicap is a valid training system. I think I was dozing at the point where it was explained and just thought it was presented as part of a discussion of competition, which it must not have been, so my bad there. But I absolutely stick to the point that no MMA fighter would fight someone in the ring, especially for title belt, if they were artificially handicapped in some way. If you think any MMA fighter would do that, you have a problem with reality. And something else occurs to me that bothered me during the movie. The whole picking of the ball scenario just didn't click, and it made for good theater to make the audience think that the magician could control the picks, but in reality any switches would be noticed pretty quickly, and in any event, a fixing scheme wouldn't stand up to scrutiny in such a wide-open arena.
Say what you will, like I said, I liked this movie. Any movie has flaws, some more, some less. Sometimes you have to allow flaws to keep the plot line intact, as in this case. But I don't take anything away from a very good movie. And BTW, I think Chiwetel Ejiofor's performance was awesome, as is becoming his standard. He seems to be becoming the next action hero, only on an exotic level with his mixed heritage and British accent. His performance in the very awesome movie Serenity was chilling, gripping, and eventually, heartwarming.
So, if this opinion has insulted anyone, I apologize. Just an opinion, people.
Come see a fat old man sometime!
