The Creeping Terror

The Creeping Terror (or The Crawling Monster) is a 1964 American horror film directed by and starring Vic Savage.

Plot
An alien slug creature begins attacking the residents of a small American town.

Why It Sucks

 * 1) The movie's sole purpose was to make money. Vic Savage (under the pseudonym A.J. Nelson) used his familial connections to attract investors with the promise of a part in the film.
 * 2) The movie's production was troubled.
 * 3) * When the costume designer wasn't paid, he left and stole the finished costume, forcing the crew to hastily construct the inferior model used in the final film.
 * 4) * Several of the actors wearing the monster costume fainted due to heat exhaustion.
 * 5) * The film was planned to be shot at Lake Tahoe, but they were eventually forced to shoot at a muddy pond instead.
 * 6) Terrible acting: no one in the film shows any emotion, or reacts realistically to anything. Heck, at one point, one of the actors can be seen laughing as he gets eaten.
 * 7) The film's recorded dialogue was apparently unusable, so the entire movie was just narrated.
 * 8) * Said narrator seems to have ADD, constantly pausing to talk about other topics.
 * 9) The soundtrack doesn't fit the tone of any of the scenes.
 * 10) At one point, reversed stock footage of an ICBM launch is used to represent an alien ship landing.
 * 11) The monster is difficult to take seriously, considering it resembles a carpet.
 * 12) Everyone in the film is stupid, incompetent, or both.
 * 13) The people the monster eats don't actually get eaten; they climb into the monster's mouth.
 * 14) A lot of plot-irrelevant scenes drag on and on for no reason.
 * 15) The monsters are defeated in anti-climatic ways: one by a hand grenade, and another by hitting it with a car.

The Only Redeeming Quality

 * 1) The film is so bad that it's hilarious.
