I really don't know how to rate this movie, as it is an odd mix of cheesy, dorky stupidity and wild, demented genius. As you no doubt already know, it chronicles the invasion of a small town by sinister clown-like creatures from another planet. Local teens try to warn the authorities, but the mean police chief won't listen.... as one of the Chiodo brothers says in a commentary, the storyline borrows heavily from that 1958 classic, "The Blob."
But that barely begins to describe "Killer Klowns." Clearly, it's a parody of 1950s sci-fi/horror movies, but it's more than that. It's ... well, it's Killer Klowns from Outer Space. A one-of-a-kind effort that defies easy categorization.
The acting ranges from good to awful (John Vernon steals the show as Officer Mooney) and the sets are often no better than you'd see in a community theatre production. Photography is surprisingly good. The soundtrack is fun, in a 1980s way.
I really enjoyed this movie, but I can't give it more than 3 stars because it's so cheaply produced, and the acting is just AWFUL in places. Buy or rent a copy, get together with some friends, some pizza, and beer and enjoy it for what it is: a wild, weird exercise in goofy humor.
