- The way how Anakin turned to the dark side.
- The continuity errors with the OT.
- In ROTJ Vader says: "You don't know the power of the dark side". It sounded so cool and powerfull. I was hoping in the PT I would see the ultimate dark side of the force, but I didn't.
- That I didn't see Anakin "hunt down and destroy the jedi knights". (Oh wait, we did, he killed unarmed padawans).
- I was also hoping to see the battle in which the rebels steel the blueprints for the death star as told in the crawl of Star Wars (ep IV).
