Log Jammin II
One of the few times sequel > original.
God Father II
Aliens
Mad Max II
what i miss?
don't go star trek or star wars on me - lots of the sci-fi has gotten better cause of budget, and better writers/directors.

If you have never seen
Enemy Mine
I'd highly recommend it. and not the mst3k version. you might recognize the names of the primaries.....
