I used to like the prequels (well, I still do... in their own way... nostalgia) but they honestly pretty much suck.
As much as I am not bothered by the changes (many of them illogical... a few I AM BOTHERED BY: Hayden in ROTJ!!! ARRGH! *spits*)
It's absolutely necessary to have a good (possibly high def and Lowry restored) quality version of the OUT(Original Unaltered Trilogy right?) available... It's something highly required.
I don't necessarily like nor care about anything EU because most of it is just not the Star wars feel, get it? The video games are okay, except for most of them in terms of design and crap like that... never mind.
