I don’t even have to think about it. Castle of Fu Manchu is “White Noise: The Movie.” It is a soulless, empty husk of a movie where nothing happens, like at all… I’d rather watch Manos, Monster A-Go-Go, and Red Zone Cuba unriffed back to back then ever watch that episode again.
Invasion of the Neptune Men. That turd was made by a major studio. Bad dubbing, annoying children, repetitive use of stock footage, no characters at all, just hideous.
The Starfighters is my least favorite. Not the worst on a technical level but it’s so devoid of entertainment and clearly not even interested being anything but a waste of money.
It’s hard for me to divorce the quality of the movie from the quality of the episode. But Monster A-Go-Go is so much fun as an episode. Castle of Fu Manchu just feels like a slog.
