This one has it all, including the 'right' name -- "The Howling II: Your Sister is a Werewolf".
You know it's bad but you keep watching; it's all wrong but you have to respect its misguided efforts to entertain.
Whether you agree or not, do you know any other contendas in the same league? (please don't list "Plan 9" as that one's not so bad it's good, it's so bad it's BAD).
I only barely liked the Troma films because they were intentionally trying to make camp films. They were fair, but them being so blatant about it turned me off.
I loved the B movies of Jim Wynorski and Fred Olen Ray much better.
Oh, as for contenders, you can include any of the Andy Sidaris movies with the Playboy bunnies as federal agents. They were "bad", but they had some bodacious babes which cancelled out the silly plots and dialogue.
1. Amityville Horror. The original, not the remake or sequels. Silly beyond belief.
2. JFK. Yep, the Oliver Stone(d) movie. The most cliched, hammy acting I've seen in ages. The whacky conspiracy theories and the glamorization of the kook Jim Garrison is beyond funny.
It sure is. Troll 2 might be one of the most "famous" bad movies out there but I have always found it to be rather dull. I remember I was looking forward to see it after watching some of the scenes on Youtube, but thats just it, I had seen the best part of the film and the rest was no near as funny or entertaining it was just boring. Now, Howling II is pure entertainment from start to end and I fell in love with it a couple of years ago and its just keep getting better all the time.
The Toxic Avenger is not a bad movie or even a "Its-so-bad-its-good" film, but a full blown masterpiece of modern cinema that should be studied in schools all over the world along with Arnold Schwarzeneggers Commando (1985) and Slys Cobra (1986).
"Village of the Giants" (1965) also qualifies as one of the greatest bad movies of all time. It's a bad movie and, yet, it's thoroughly entertaining, and entertainment is the name of the game.
