Me, being the 80's freak that I am.. have to at LEAST say..
Back to the Future.. 
Robocop.. and 
Tron.. f'n-A man.  
I still haven't taken the time to get my ass to watch Blade Runner all the way through.  Yes I'm a loser, I know 
Aside from oldschool... 
Event Horizon
The Matrix
War of the Worlds (remake with the tool Cruise)  I was VERY impressed with it.
Fire in the Sky  Wasn't a lot of action.. but man it scared the piss out of me, especially knowing it was based on a true story.
Hitchikers Guide to the Galaxy (the new one)
And for future sake.. This has to be good.. I don't see how it couldn't..
