i love christopher lloyd in this

Totally agree.
He's awesome, and the flick is mighty cool. Just purchased a copy of it on VHS a few months ago.
Originaly got sucked in by the nice die-hard slasher cover with the pair of scissors and all ...but really enjoyed its offering.
Not an Einstein of a movie, but still some great suspense.
Don't think this ever made it on DVD.

i would say he's quite subdued in this flick

The group therapy sessions in this reminded me of "Color Of Night", and Christopher Lloyd's character in this reminded me of Buck (Lance Henriksen) from that movie.
