This film is much beloved by some as a campy 80's classic. I guess it depends on your sense of humor but I just didn't get it. This is no Ferris Bueller's Day off or Weird Science. I found TerrorVision to be painful to watch. Comedy is a tricky thing to pull off, especially when it's the over-the-top kind. TerrorVision feels a bit like Pee-Wee's Playhouse with its brightly colored sets and cheesy over-exuberant characters. The only problem is that it's not nearly as funny as Pee-Wee nor quite as subversive.
The monster in this movie can best be described as a big pile of oozing flesh. There were lots of great puppetry effects in the 80's such as The Ghoulies but the way this monster is constructed makes it difficult for it to convey terror or any other emotion. It's sort of like the Grimace in the old McDonald's commercials whose only way of communicating was giggling and jumping up and down. Yeah, this is that kind of monster.
To be honest, the acting is fine. The cast is full of character actors such as Gerrit Graham [Child's Play 2, Demon Seed], Diane Franklin [Bill & Ted's Excellent Adventure, Better Off Dead] and Mary Woronov [The House of the Devil, Death Race 2000]. There's also the adorable Chad Allen who was also starring in the TV Drama Our House the same year this film was made. They give it their all, and then some. It's just that the screenplay doesn't have the kind of humor that works for me.
So, give it a shot if you like uber-cheesy 80's movies. Just be forewarned that there is barely any horror in this one and lots of groan-worthy humor.
