Puppet Master
The puppets are cool, but the movie on the whole is pretty lame and padded with psychic visions and fairly boring sex.
Puppet Master II: His Unholy Creations
Nothing special, but it's a lot better than the first film, and makes for decent time waster horror film. That ending was random as hell batshit insanity, though.
Puppet Master III: Toulon's Revenge
Now that was pretty good. Puppets vs Nazis is a hard concept to go wrong with.
