3. ROTS
4. ROTJ
5. AOTC
6. TPM
Empire rocks. Hoth is destroyed, Solo through the asteroid field, Cloud city betrayal, Han encased in carbonite, Luke finds out DV is his daddy and loses his hand like his pappa.
ANH - The first ever and the beginning of Lukes training.
ROTS - Harkens back to the original three for action and overall script. We find out how Anakin becomes DV.
ROTJ - Luke destroys the Sith and DV lives up to his destiny of restoring balance to the universe. Princess Leia in a metal bikini, Luke kicks the crap out of a raptor.
AOTC - The most romantic of all of the films but it also has a lot of information. Boba Fett, the clone army, Yoda fights.
TPM - Darth Maul is about the only thing good here. Not surprising because they have to set up the whole story and those are usually the worst. Like a TV pilot. After 4,5 and six were made I'd still expect more. Also three words against it; Jar Jar Binks. 'Nuff said.
