The stylistic choices that switch from blood and gore to Disney-like cartoon fantasy and then back again totally confused me. After viewing the movie, I didn't know there was supposed to be a love triangle until I read other reviews. If it was a love triangle, why did the guy and the blonde girl keep referring to each other as brother and sister??? And was the happy ending with the 2 of them together just a fantasy like when they were kissing and bullets and grenades were magically flying around them??? Or did they really survive?
