I saw all six when I was really young; I was probably around 13 when I saw RotS.
That being said, I never really noticed the bad acting (in the prequels) or how ridiculous Ewoks > Stormtroopers really was.
Recently, I rewatched the prequels for the first time in years. All I can say is HAHAHAHA! I never noticed how bad the acting really is. Don't get me wrong, I still love the movies, but during Episode II, my sisters and I would just relentlessly torture Anakin/Hayden Christensen on his "acting."
The originals trump all.
So do Ewok Adventures: Caravan of Courage and The Battle for Endor.
