I have a 52" HD Widescreen TV, so this non anamorphic has a big effect on me. The first few days I would just skim through scenes and at first, I really was kinda down, cause it looked pretty bad. So the first weekend, I didn't watch any of them movies and just tinkered with my color on my TV, just for watching DVD's, and I found one option: Vibrant. All of the sudden the DVD's looked pretty damn good, as the colors were really nice and really stuck out again, the fleshtones were alot more detailed, and the picture look pretty damn good for non-anamorphic, not great, but good enough.
So the last three weekends I have watched SW, Empire, and Jedi, and I have to say I am content with this set. The only scene that really look too grainy are parts of Hoth when they just show the snow, and parts of Tatooine when they just show the sand, but other than that, and I am being a 100% honest, I have really enjoyed these movies, and dont' regret buying them one bit now.
As for the future, if Lucas does remaster the O-OT, I would still buy it, but I am not gung ho crazy like I was since 2004 when I was trying to find decent bootlegs. At this point, I am a 4-6 man, and I think that is the reason Lucas didnt' want to release these versions, there is nothing in there that ties to the PT, so I really dont' think about all the PT bullshit like I do when I see Hayden in ROTJ SE, and all the stupid CG crap that sticks out of a 30 year old movie.
I know they aren't perfect, but I actually don't have hatred for Lucas anymore, I just don't think about him and all his crap anymore, as I have checked out as a SW fan, and in a sense the way he has treated me, I haven't really enjoyed anything with SW since 1983. So I have said many of times, George may have won the battle by putting out the O-OT in non-anamorphic this time, but he has lost the war, cause if you read my sig, that is the only money I will be shelling out for SW anymore, and that is cause Lucas created this whole split in the fanbase.
