It's a well known fact that George Lucas took it a little bit too far in ROTJ, like the Jabba court sequence that looked like an over-the-top episode of The Muppet Show and the horrible dancing number with contemporary big band show music. The 'enhancements' to the 1997 and 2004 SE didn't remedy that. Instead they made it worse, considering that I had grown accustomed to the original version of the movies with all their glitches and little defects.
There is still hope that 2007 will see a OOT release that does credit to these movies. They deserve it!
