They replaced the guy playing Vader?!? Man, I didn't even get that far. I stopped watching a little more than halfway through IV. The Jaba scene was weird, the new CGI'd animals was weird, the hovercraft was all snazzy and Anakin-like...there was only so much I could take.

You should really check out the animated movie. It's rather entertaining, 80's rock pop soundtrack included. Leonary Nemoy, Eric Idle, and Orson Welles (yes, THE Orson Welles) are some of the more famous people to lend their vocal talents.
