This movie feels surprisingly modern and holds up incredibly well. There's some still surprisingly horrifying stuff even by today's standards. Vincent Price is incredible in this.
This is a movie that for the first hour and fifteen minutes is a meandering bunch of the protagonists being terrible, strange action scenes, and just bizarre scenes in general. The last 15 minutes is an incredible combination of utter nonsense that's just stunning.
It's a not-great movie with some memorable scenes.
