In retrospect, this film is pretty bad. However, I was introduced to this film as a kid as it was laying around in VHS. It absolutely terrified me! Look at the death scenes still freaks me out. However, I do remember seeing it as an adult and remember how corny and bad it is. However, I can now appreciate it for what it is.
The Police Academy series is also pretty terrible. I mean, they're great fun and I loved them as a kid. But as an adult, I couldn't defend them in any rational way other than that they're pretty goofy and it's nice to watch completely stupid films every now and then.
