I agree with the love for
Rocky Horror
Blade Runner
Goonies
Beetlejuice
Spinal Tap
5th Element
Army of Darkness
I'll throw a couple others out there:
UHF. It's not in the same universe as any other movie mentioned, but it is 80s. And it has strong pin theme potential.
Spaceballs. Dark Helmet bash toy. Nuff said.
A-Team.
MacGyver.
Quantum Leap.
Sliders.
And maybe Dazed and Confused, just for the hell of it.
