I was just talking about the Halloween series on the SECr so I came over here and saw this thread. First post I saw this.
Halloween III: Season of the Witch
This is one of the worst horror movies of all time, and that is saying something for the genre. I've seen every Halloween at least 3 times, except this one. Watched it once, threw it in the fire, and paid the Movie Gallery the $7.50 for the lost VHS.
Honestly I would choose watching the following abortions over H3SotW.
Killer Clowns from Outer Space
Leprachaun in the Hood
Blair Witch 2
