Red Zone Cuba is a rough one. Several of the Coleman Francis ones are bad, but that one's the worst.
Creeping Terror has some slow parts, but it's saved by how absurdly awful the monster is, like, in a funny way.
I'd say some of the Season 1 stuff is the worst, though. Season 1 is rough because the show was still very much finding its legs. So, the riffing was a lot slower, Joel was (purposely) a lot "sleepier," Crow was much more baby-Crow-like, and they had a different Tom Servo voice (J. Elvis Weinstein, who also played Dr. Erkhard or something). Especially if you're used to Kevin Murphy as Servo, going back to Season 1 is rough. Plus, they were a lot less focused on controlling the content. They just picked really bad movies, without regard to how they were bad. A bunch of that changed in Season 2, after they did (I think) the Sidehackers. Prior to that point, anyone in the crew could just suggest an episode, and they'd write the riffs and then film it like a week or two before. But that episode actually features a rape in the original film, and they had to cut around it, which made the movie even more awkward and weird (it's still entertaining as a film, albeit bleak). After that, they agreed to all watch a film before it made the list of what they'd riff that season.
Anyway, in Season 1, there are just some real stinkers. Robot Monster is one, The Slime People is another. I've only watched Season 1 episodes, like, once, so I don't remember them very clearly, but they're generally pretty tough to get through. The riffing is more sparse, and not as funny, and the films are, in many cases, a lot worse. They're sort of bizarre artifacts, if you're curious about bad films in general and some of the crazy crap people have tried to turn into films (seriously, just look up Robot Monster for what I'm talking about), but they're just really hard to watch.
I actually think Robot Monster is way, way worse than Manos, which at least has sort of a goofy charm to it once they stop driving and get to the weird-ass motel.
Cool, thanks.
Yeah, there were supposed to be opening film credits spread out over that long driving scene at the beginning of the film, but the guy who made the film forgot to put the credits in. Lmao!
