I need to add George Lucas to Mel's list of film-makers we want to kick in the nuts.
Let's get one thing straight: It is okay to digitally remaster old films. It gets rid of the grainy quality, makes it a better viewing experience, and the sound is quality.
However, it is NOT okay to change the actors playing characters. Seriously. At the end of the digitally re-mastered Return of the Jedi, the remastered version of the remastered version (i.e. the re-re-release in 2004) the ghosts of Anakin Skywalker, Yoda, and Obi-Wan Kenobi appear. Cool. Only Anakin is being played by Hayden Christenson. Yeah, you heard me, an actor that wasn't (probably) even born when the film originally aired! And for some reason, this really incenses me to the point where I was fuming and did nothing but rant and rave for a good ten minutes about the absurdity of it all. How could they do that?! I can only add that the only film's saving grace was that they kept Alec Guiness and didn't change him for Ewan McGregor. That would really have gotten on my goat...
