How would you evaluate his horror filmography?
Re-Animator is a lot of fun. Short runtime, great gore, some nudity from the lovely Barbara Crampton, quite funny too.
From Beyond is maybe my favorite of his. The same formula as in Re-Animtor (with much of the same cast). Short and sweet, gory, funny, some sex appeal.
Dolls is just okay. Didn't care for it much.
The Pit and the Pendulum is decent. It had some potential but never really rises above being just okay.
Castle Freak is alright for a direct-to-video horror movie.
Dagon comes close to being great. I really like it. A good adaptation of The Shadow over Innsmouth. Sadly the low budget shows and it doesn't quite make it in the end.
