I liked it the old way, but I also like new X-Wings, Jabba scene, and restored picture quality even more. The movie's better, I'm happy, life goes on.
So the benefits outweigh the costs for you, eh?
Well, yes. The re-done movies are indeed shinier. They have more bright lights and loud sounds. The explosions are more explosivey. That's a definite gain there.
What's lost? To me (and why should I care about what first-time viewers think when I can only judge a film on my preferences and not their ignorance?), the Han-Greedo scene edit fundamentally changes the character of Han Solo. This is not a relatively trivial change from 10 X-wings to 50, but a series-shocking reversal of character.
What Han was, was a rogue who will smuggle if there's money in it, kill in cold blood, deal with gangsters, and generally do what's in his own monetary interest.
Lucas tried to make Han a shinier, happier person by not having him strike first when being threatened by a blaster, but instead making sure that Greedo's intent was to kill him, and only
then acting. He was insiting on the proverbial smoking gun.
This changes his character. And it changes his character for the worse. With the new Han, the character development from rogue to hero over the course of the movies isn't as intense because we begin with someone who refuses to kill when held at gunpoint.
So... back to cost/benefit:
More, shinier spaceships.
vs
Radically different Han.
Give me my good old time Han. It's the characters and the story that matters anyway, not the FX.
ps. I won't even get into the added Jabba scene... who once was a mysteriou and feared gangsterous agent who turns out to be an imposing and viscious slug-thing... becomes a sniveling wanna-be wise guy who lets the sensitized Han push him around. Ugh.
