No particular order:

Terminator
Blade Runner
Serenity  (yes - I do think it is among my all time favorites now.  The STORY is good).
Highlander
The Matrix
Logans Run
12 Monkeys
Planet of the Apes
Star Wars
Chronicles of Riddick

Crap that's ten isn't it?  I haven't even gotten to Alien/s, 2001, Invasion of the Body Snatchers, the Blob, Predator (cheesy but classic), Close Encounters, ...  

The problem is I often like the concept (or a key concept) or innovation better than the whole movie.  For example, some elements of the Thirteenth Floor are much better than the Matrix, but the Matrix executes better.  Riddick and Serenity are just cool and different, good stories.  12 Monkeys is just interesting - It might not have made the list if I hadn't watched it recently.  I also thought Total Recall was cool, if flawed.

Star Wars is just there because at 7 years old when it came out it changed my world completely.

Then there's movies for which the director should be shoved through a wood chipper for destroying a classic book, for example, Starship Troopers.

I forgot- Independance Day.

"Welcome to earth!"  "And what's that smell?"

Jim

Serenity
The Empire Strikes Back
Alien
Star Trek II: The Wrath of Khan (KHAAAAAAAAAN!)
Gattaca
The Matrix
Blade Runner
Cowboy Bebop
The Fifth Element
Terminator 2

Not necessarily a list of the 'best', but they just happen to be some favorites.

Aliens
The Terminator 1 & 2
Robocop
The Thing, though I consider that more horror, but I guess since it's an alien it's in the sci-fi genre too.
War of the Worlds (2005)
Serenity
Star Wars ESB
Chronicals of Riddick was pretty kick ass and amazing to look at.
Do I even need to say the Matrix? I won't say the sequels, but I thought they were cool enough. And I did like how it ended, unlike most people.


Hey that's ten... guess that's my list. Of all time? Eh, I don't know... this is off the top of my head.
