Although the 70s probably had the more original and better made horror films, I had to go with the 80s. I own more 80s films and they get re watched more then a lot of the stuff from the 70s. That was when the slasher genre really hit its high point, including the Friday films and its many sequels, which I love all of them! It was also when gore and special effects were at the top of their game as well, which can always make a bad film good. It was when horror films become really fun to watch, and what got me into the horror genre. Unrelated, but the 80s was also the best time for cartoons; G.I.Joe, Thundercats, Masters of the Universe, Transformers, Ninja Turtles, C.O.P.S ect. Damn we were spoiled back then! I feel bad for kids these days who only know of Pokemon and all that other Japanimation crap.
