The Battlestar Galactica 'movies' which haven't aged well and I since discovered were just episodes of the TV series put together. At the time though, any film involving spaceships and lasers was 'skill'.
I agree! I find The Goonies just as good as when I was a kid, better even in some ways as it's so nostalgic.
Ones that have disappointed:
The Watcher in the WooRAB
Labyrinth
K9
Grease
A Nightmare on Elm Street (still like it but it doesn't terrify me like it did)
Most of the Carry On Films
Also, not a film but does anyone remember the 'Five Children and It' series? I LOVED that and got it on DVD to relive this great programme I remembered and cringed all the way through it.
Ones that never will (Goonies already a given ):
Back to the Future
The Terminator and T2
The Haunting
