Plus, the 80s was when Star Trek: The Wrath of Khan came out, and that's a definite classic. XD And Pee-Wee's Big Adventure! And The Little Mermaid! I mean, man. A whole DECADE? How can you pick just one!
THIS! Especially Splash. + Hellraiser, A Fish Called Wanda, Willow, Scarface, Platoon, Indiana Jones... and almost everything else released at the time. It was the best time for good cop shows, too. The 80s has the best of everything. Even the porn was awesome (in its cheesiness).
I growed up on (?) Back to the futureXD I watched it many times and I can quote from it. It's story is fanastic Does someone hate 80s? I think 80s was the one of the best periods (at least in the music)
I would have said Labyrinth, but I watched it at Christmas at first I think that isn't so famous in my country...
