This is an mid-1980s horror comedy indeed, except it was lacking both ingredients actually. It is, however, a very typical Charles Band movie, for good and worse. Was "Ghoulies" a memorable movie? No, not by a long shot. It was just too silly and empty to really be entertaining.
"Ghoulies" is about a young man who inherits an ancestral home. A house where black magic was used to conjure forth demonic creatures. Lured in by the dark magic, the young man unleash the demonic beings once again.
The characters were lacking personalities and depth, but fitted right into the rest of the movie though. The acting performances were nothing impressive either.
As for the creatures, well they were probably impressive back in 1984, but by todays standards not so much. It was puppets, blatantly obvious, and again typical for Charles Band. And the special effects, well let's not even go there.
This movie wasn't particularly entertaining, and I will never watch it again, that much is certain.
