Okay, I haven't seen this movie but I have read and talked to people who have... and I just have this to say about the rating it has received on IMDb:
Don't rate it as a 10 or a 1... it makes no difference. IMDb calculates votes on a weighted system and most likely, on such a 'political' film, they will disregard the votes from users that display a history of voting tens or ones on certain other titles similar to this one.
Just watch the film and give it your honest rating... odds are it isn't one of the greatest films ever made in the history of mankind (10), nor is it the lowest turd ever to stink up the silver screen (1), GIVE IT AN HONEST VOTE AND STOP THINKING YOU CAN BULLY THE SYSTEM. I've seen it with The Godfather and LOTR and Shawshank people too and it's ridiculous. Seriously, if you are incapable of viewing a film outside of your own impassioned feeling-of-righteousness over it, then you have no business even venturing to rate it on IMDb. The rating it receives here is also not the be-all end-all of the film's worth, and thinking that you are accomplishing a great deal by voting for it to such an extreme is idiocy.
Alright that's my rant... give this film a chance. I'm a Bush-fan and I gave Fahrenheit my honest rating as a film, not according to how much I disagreed with its ideals.
