You know how most movies from thirty years ago suck ass? Planet of the Apes isn't one of them.
Go watch. Not the shitty, shitty, shitty, shitty remake. The original. It is good. Really good. And very, very thought-provoking, even today.
Especially if you've ever looked at a gorilla in a cage and wondered if the cage is there to keep him in or keep you out.
I don't want to spoil anything, but let's just say that despite the title, Planet of the Apes is not about apes. It's about humans.
Also, "YOU MANIACS! DAMN YOU! DAMN YOU ALL! YOU BLEW IT UP!"...is a movie quote that will stick with you forever. That's why it's everywhere.
The sequel, Beneath the Planet of the Apes, is not bad either. Not as good as the first, but definitely not bad. Can't say the same for the third movie, though...
Egad...the third movie...so awful...
Still waiting on the fourth and fifth.
