I just saw this today, and wow. What a powerful, powerful movie. It is only the third film that has ever made me get teary (Hotel Rwanda and Ray are the other two). Perhaps because it's so near to memory, but it is an incredibly intense film, raw and emotional. Anybody else seen it? I haven't seen any of Oliver Stone's other films, but if they are on the same level as this one, it's worth looking into.
I'd say it's definitely worth $6 or $7.
