OK so it's not really horror, but it does use SF/Horror tropes at times. in the new Dave episodes a bio-photo copier creates a creatures that looks not unlike The Thing in one of it's incarnations from the Carpenter film.
I watched the new feature length episode on Dave (available now on UK player.) after reviving Holly with an unfeasibly large floppy, the crew do a runner and meet up with the rest of the cats who are at war. A B-movie SF plot really but it's fun and had some splendid gags.
Moo.
I don't think I've ever seen an episode of this. Just recall a bit of a scandal about a cast member pinched for dealing coke or something?
