It's that simple, really. The 15 Rating it received in the UK is another example as to the uselessness of the BBFC these days, and adds more weight as to why it should be disbanded, and a new ratings system should replace it.
Some people will pointlessly argue that quick cut photography ALWAYS lessens the impact of violence/harsh scenes...they would be wrong.
That's my 2 penneth on that matter. Now, this movie?..too harsh violence-wise for a 15 rating, that's for sure. The sex?...depicted in ways unsuitable for 15 year old eyes...again, a sure thing. Hey, I'm no prude...but the main "hero" is a coward (not human, a coward), and a scumbag. The morality of the way he conducts himself sexually is something that will probably go over most 15 year old heads. Now, some out there are smart - don't get me wrong...but to most people that age hormones come first...so this is why I say the depictions in this film are not good.
There's basically no positive messages in this film. Forrest Whittaker is (of course) great...but that doesn't mean the film is! At the end of watching this film I would think you'd feel soiled...and left with the feeling of "Well, that was a unpleasant waste of time."
Don't bother with this film imho. Watch something entertaining, or just plain good instead lol.
