Well Charon... you definitely set me straight on that!
It's funny, now that I learn it's gratuitous and unrealistic the movie loses a lot of the shock value and becomes a lot sillier. Actually, now I'm a little pissed off that they'd go so over the top with violence. Heck they even show children getting killed, which you rarely see in movies. I need to mull on this more to settle on how I really feel.
