In my haze, I realized that Fear works best if you constantly scream at the characters like a douchebag. Like, "Ah, no, Judging Amy don't answer the door" and "Ooh, Gil Grissom, kick Marky Mark's ass." It was glorious to do this alone in my living room; my wife probably disagrees. I'd probably die from ecstasy if I did this in a movie theater.
Fear is one of those movies that I watch because I always forget about what happens. Then, I watch thinking that the thing will improve. It doesn't. Then I kick myself for having watched 35 minutes of Mark Wahlberg and his stupid menacing whimper-whisper.
I will say this: The ending is truly phenomenal. William Peterson throws Wahlberg out the window, but it looks like Wahlberg is blasted out of a cannon. And I love the crunch sound at the end. (Go to the 1:45 mark.)
