I just watched Filmroasters' riff of Cat Women of the Moon. Four and a half out of five stars. It was a very well done riff and the fact that it was free didn't hurt either

This riff had a lot of nice, sharp lines in it; the timing of their jokes was excellent and the interplay between the group was superb. A couple of moments had me laughing out loud. Even more than Zardoz, I got a real sense of group camaraderie here. They really seemed to be enjoying themselves, riffing the heck out of this awful movie, laughing at each other's jokes, throwing zingers at the screen like nobody's business. And the movie itself was a real dog. Terrible acting, cheap sets and special effects, cliched writing. In other words, perfect riff fodder. And the spider. Dear Lord, even for the 50's that was a bad effect.
There are a good number of sex jokes and fart noises in this riff, but unlike some groups they don't use it as a crutch. The riff has a solid mix of both highbrow and lowbrow humor.
My only complaints are the repeated "I'm a scientist" line and I didn't laugh quite as much towards the end, though that was probably the movie's awfulness wearing on me as much as anything. And the riff file was enormous. It might have helped to compress the file or chop it into sections. Other than that, great work.
Overall, I'd highly recommend this riff. And I'm interested in purchasing more of their riffs in the future.
Some of my favorite lines:
The "In-a-Gadda-da-Vida" reference at the beginning had me cracking up.
All right, now get in the sewer!
I think the moon is stalking them.
"It works." The moon works.
Is he wearing a colostomy bag?
"Our ancestors made one fatal error, Helen." Carrot Top.
"Where've you been?" Oh yeah also hi ladies who tried to kill us.
Shut up, I'm trying to go!
The reference at the end with the lost crew member. Yeah, they seemed pretty nonchalant about losing one of their own.
