Technically, you could call The Texas Chainsaw Massacre and Halloween "B" movies due to their extremely low budgets. I have a hard time considering them "B" movies for obvious reasons. If I had considered them to be "B" movies, they would have been at or near the top of this list.
1. THE CREATURE FROM THE BLACK LAGOON
2. NIGHT OF THE LIVING DEAD (1968)
3. DEAD ALIVE AKA BRAIN DEAD
4. RE-ANIMATOR
5. BASKET CASE
6. THE EVIL DEAD
7. CLASS OF NUKE 'EM HIGH
8. BLOOD FEAST
9. THE TOXIC AVENGER
10. THE BLOODSUCKING FREAKS
