(thinks) Oh, I dunno... I'm pretty well versed in '70s stuff. I grew up on all the B-flicks. Giant spiders, atomic bugs, werewolves, zombies, vampires...
These are all my monsters. Where have I seen that before?
You can argue plot like you can argue George W was a good president.
Bruiser has a plot. Most horror flicks don't have a "plot" in my opinion... they have a story mechanism that allows them to fill more body bags. '80s flicks like
Nightmare and
Friday... can you say these have a plot? It's a pornographic bloodbath with some witty oneliners. Masterful, but I wouldn't consider it literature. This isn't bad or wrong.
Night of the Living Dead is the best zombie movie ever made and it consists of stupid white people getting killed, the first smart black guy in a horror flick, a strong female character kicking ass... and all sorts of awesome flesh eating.
I never leave NotLD feeling like I learned something, but I'm way entertained.
