Stephen Georg’s review published on Letterboxd :
MST3K is definitely hilarious, but Squirm is pretty average as far as they go. The real treat is probably the short that precedes the film, A Case of Spring Fever, a 1940s spot about a man who wishes springs had never been invented. He gets his wish when Coily the spring sprite removes all the springs in the world. It's as bizarre as it sounds.
Anyway, worth watching as an MST3K fan, but there are definitely better ones out there to start with.
