My favorites, in order
Attack of the Clones:
Reasons: "Around the survivors, a perimeter form."
Drunken Yoda style combat.
The ship-mounted weapons look way cooler than in the other movies.
The entire arena scene.
Jar-Jar Binks is the ultimate evil

Mace Windu gets a bigger part.
A New Hope:
Reasons: Great start to a series.
For its time, the special effects were magnificent (like the training droid sequence)
Revenge of the Sith:
Reasons: A bunch of cool lightsaber battles.
The giant riding lizard.
Wookies are the only reason Yoda lives.
Phantom Menace:
Reasons: Cool lightsaber battle.
Awesome special effects.
Podracing.
Return of the Jedi
Empire Strikes Back
I like them all.
I also like the books, though I'm really upset that they changed the rules on how lightsabers are made. The series was supposed to be comprehensive, never disagreeing with itself. Then someone decided that the gems that made lightsabers were magical rather than just being a crystalline lens. Also dislike the way that Timothy Zahn messes with other peoples' writing, though Outbound Flight was awesome.
