A mad scientist and his assistant (Jeffrey Combs) create a device called The Resonator that allows them to see things beyond reality. Unspeakable, horrible things, which cause the mad scientist to be decapitated and his assistant put in a nuthouse for the murder.
The doctor who treats the assistant gets him out of the nuthouse and they, along with a detective (Ken Foree from Dawn of the Dead) head back to the research house to restart The Resonator. Things get cray-cray.
As in Re-Animator, Jeffrey Combs is great as usual. Ken Foree is fun to see outside of Dawn of the Dead. The rest of the cast is pretty forgettable.
The story is fairly bland, but the visuals are appropriately extreme. I like all the gruesome body configurations or fleshy flesh weirdness. I don’t even know how to describe it. The “beyond” stuff is all mangled. The mad scientist comes back as a flesh creature with a little head dingleberry. I feel like I’m not doing a very good job of explaining this.
Anyway, it’s pretty out there and mostly fun to watch. It has echoes of Re-Animator, since it’s directed by the same guy.
