I didn't want to sound too melodramatic, but it kind of culminates in Anakin's character - and how we as an audience see his "rise" and fall (and redemption):

Way back in the 80ties, when I was a kid, some years too young for "Return of the Jedi" (but who cared then, the other two movies had a low age rating), my buddies and me had read about this film: space ships and stuff, what could be more fun?

I had no idea of what, who, why, when, back then - just some weird aliens, a bunch of heroes, battles and Ewoks (hey, kids love teddy bears!) - and instant "love" for lightsaber fights ;-)

so I knew Vader was Luke's father before seeing "Empire", years later on VHS, but it somewhat stuck as important "turning point", similar to the "trial in the cave" ...

Fast forward about 20 years (of yearning for new movies) - Anakin's story unfolds ... and it is a creepy tale: some worship him (offscreen?), others fear(?) him, his spouse takes a mass murder of sandpeople light as a talk about weather, his "friend" and "brother" doesn't even care to deal the deathblow (maybe killing all those younglings fried Ben's heart) - then we see Vader (do we cheer or hiss here?)

Strange enough, I could accept Vader's redemption back then, when he disobeyed the Emperor and saved his son - but now it is not so easy, thinking about all that bad stuff he did, and without remorse ...
