I had been meaning to watch this for probably two years and, seeing it on the big screen, it did not disappoint. Based on a Lovecraft story, Re-Animator takes a zany concept and plays it to the hilt, yet somehow never really veers into goofy territory, usually opting instead for a more dark and sinister brand of humor. Very well shot, at times almost treading into Cronenberg territory, with mostly strong performances, particularly from the perfectly cast Jeffrey Combs as Herbert West. His performance almost ranks up there with Ted Levine in Silence of the Lambs for its creepiness factor.
The score work here is also quite memorable, although perhaps too openly influenced by the work of Bernard Herrmann, particularly on Psycho.
Apparently Re-Animator spawned two sequels, but the original is so great that I'm not sure I even want to bother with them.
