I love horror movies especially the cheesey type of horror movies that are so stupid that they are great. I do prefer the ones that would always appear on SyFy, but any other type (that is not like the ones on SyFy and look a lot better) is fine too.
I actually watched this one several years after it was released, but I think it ticks all the check marks you want.
The Gate (1987)
Don’t forget part 2!
That’s even more terrible than original.
