Goddamn that was an awesome movie.
Yeah, the characters were great, save for the Imam and his 3 cannon fodder. I guess Hollywood couldn't be arsed to write interesting Muslim characters before 9/11.
As everyone have already pointed out, there were some really good lines too.
Visually it left me impressed, especially when you consider it's a 12 y/o movie. The solar effects during the first half and Riddick's vision were kinda iffy, but tolerable.
My favorite scene is probably the booze trader's death scene.
Most shocking scene is the one Demi mentioned. Using menstruation as a plot device gave me a pause. Kinda ballsy.
