"Logan's Run" did not hold up at all.
Nor did "Westwood," "Andromeda Strain," or "Alien."
Basically, I think you have to get to the 1980's before Sci-Fi movies start holding up. Then you get "Blade Runner," "Predator," "Cocoon," "E.T.," "The Thing," "Buckaroo Banzai," all the stuff that really held up (with the exception of the 1984 version of "Dune," obviously.)
And "Bill and Ted."
Pretty much, if it held up for more than 20 years, it came out in the 1980's.
