David Cronenberg is another really good horror director, with the fly as well as videodrome it's really amazing and interesting just how during the 70s and 80s people really have to bust their asses to make such believable special effects like these. We can't forget Troma films especially the toxic avenger! It's the costumes, and effects on body horror that make such movie magic special at least during it's time. For now it might seem old fashion but these movies really did pave the way for movies in the future as well as inspired certain video games hence cheesy lines that Duke Nukem says.
"On the cash register we've got that 'magic fingers', Ricoooo!" "That's ME!" Hahaha. Never gets old.
Too right, you have to respect the classics. I really love the old practical effects where you had to get your hands dirty. The use of creepy claymation, animatronics and other materials really gives you a kick that you simply don't get from CGI. I think the reason so many people suffer from phobias and the 'uncanny valley' these days is because CGI is too clean and has no character. You don't see a great deal of puppetry and creative special effects any more.
