Come On
I thought this movie had a very interesting concept, however the third act was terrible. I was somewhat into it until they captured Cage. And just when you think there's a redeeming quality of the movie, (flashing all the way back to the motel) they still manage to leave it unresolved.
Now I know it's "just a movie" but if we are being led to believe that everything in the third act was a vision, then why are we seeing bits in the perspective of the terrorists when he can only his that of himself or the fate of Biel's character. And just because a movie didn't show a resolution doesn't ruin it for me. The fact that they turned it into this high adrenaline action sequence followed by no resolution does. Imagine watching Die Hard with a vengeance and right before the final scene, Sam Jackson turns to Willis and says "you ready" and roll credits.
A movie like Lost in Translation doesn't need a concrete resolution, This movie did.
