Almost seems like someone had an idea for a bland cultist horror flick script, but was told "Gremlins are big, you gotta put some little dudes in this!", so they wrote in a couple of midgets, were subsequently told that didn't count, so wrote in some slimy puppets, but forgot to get rid of the bit they'd written about the midgets, and somehow made their bland idea straight-up bad. This came out the same years as Gremlins though, so I have no idea how it was allowed to happen.
Final rating:★½: - Boring/disappointing. Avoid where possible.
