I've seen this one many times, and while I enjoy the humor and Vincent Price, I never found myself really loving this movie. It's certainly worth a watch, as it has a vibe that few other horror films do (a portion of this might be due to the era this came out), but it's not a favorite.
What do you think about this Vincent Price flick?
