Invasion of the Star Creatures!
I watched that one Summer night as a kid on the late show.
I bet no one else ever even heard of it.
Actually, it's available streaming on Netflix and in addition to 38 reviews, it has an average of 2.4 stars from over 19,000 viewers. So more people have heard of it than just you and me. In a country with 310,000,000, that means about 1 in every 17,000 Americans has seen it [and I would guess that not everybody who saw it actually rated it, and plenty of people have seen it somewhere other than Netflix.]
Anyway, not all that arcane, and certainly one of the worst ever.
