a movie is not better just because you first saw it when you were 5.
to be honest, the only thing that made me like star wars at all was the villian design, the glowing swords that could cut anything and the fact that they had something called "death star" even though it was nothing but a huge gray ball.
the story wasnt anything special, besides for the whole playing in space thing, it followed pretty simple themes. space people, space conflict, space daddy issues, space love born out of space bickering. the whole force thing was a cool idea in general, but that wasnt anything new really. comics and tv shows had the telekineses thing on for quite some time already... so space telekineses
the actors, well, they were actors and as such did a good enough job, but oh well? that was about it. im happy that ford was able to go on making good movies later.
costumes, yeah, great, black robes, robes not so black and fur suits of varying sizes. apart from the menacing vader costume, most of the stuff was pretty unimpressive.
dont get me wrong, i like jim henson-like stuff as much as anyone, but i dont think the ewoks are much better than jar jar was.
i actually prefer the pod-race scene in comparison to the death star trench flight.
im not saying the movies are bad, they arent, obviously. but im saying the new ones are underrated, while the old ones are overrated.
