Honestly, I'm glad you guys dug it. For me, though, it just completely failed. I wish I could pin it all on Keannu; usually I'm amused by him but this was easily one of his worst jobs. It can't be all blamed on him. The director had one or one film credit before, two music videos, and a Tales of the Crypt episode before making, and has had no credits since. This movie literally ended his film career.
Like I said, I tried to like this. Twice. I'm a big fan of the short story and most of Gibson's work. But everything from the pacing, the acting, the characters, and the look just felt severely off to me.
The soundtrack, OTOH, had its merits...
