My favorite is Revenge of the Sith.

What's yours?

I love em all so here they are in order

1 - A New Hope
2 - Return Of The Jedi
3 - Revenge Of The Sith
4 - Empire Strikes Back
5 - The Pantom Menace
6 - Attack Of The Clones

Here they be in my order:

1. Empire Strikes Back (Best movie of all time?!?! Darn close IMO)
2. A New Hope
3. Return of the Jedi (If the Ewoks had been Wookies instead, this could have been #1)
4. Revenge of the Sith
5. Attack of the Clones
6. Phantom Menace (Biggest dissapointment ever?!?!! Darn close IMO)

The Empire Strikes Back, naturally.

I can't believe I haven't friended you yet. Probably because whenever I see your avatar I'm already laughing.

K, we're friends now.

1) The Empire Strikes Back (all other answers are WRONG)
2) Return of the Jedi
3) A New Hope
4) Revenge of the Sith

HUGE GAP

5) Attack of the Clones
6) The Phantom Menace

Return and New Hope are pretty much equal in my eyes.

Return of the Jedi. Admiral Ackbar is The Man(-fish)!

The Empire Strikes Back is the best of the Star Wars movies by a considerable margin.

Man, if I would've known that I get 10 million yen, I would have done this a long time ago. That's like, what 15 bucks?
