Return of the Jedi is the best. The scene where Darth Vader turned to helped Luke and threw the emperor off the balcony. Touching scene. But the star of the series is R2-D2, since it always saves their asses. The prequels sucks big time and I feel that Anakin character was just wrongly written out.
Was it Part 4, that Darth Vader destroyed 3CPO? Surprising that he did that, because it was his first droid and he build in from scratch, when he was still Anakin.
I remember he just whacked 3CPO just like a stranger droid.
