I love how some fans wont give up the simple fact that George Lucas is now done with Star Wars. Yes, perhaps there will be many more versions of the films, but there are not going to be any more films, nor any remakes.
I also like how new fanboys who praise the new films, but find many "faults" with the old films, such as Animal above, continually think that the Obi Wan/Vader duel needs to be "fixed up"...It is a great scene, and you need to realize that it is not supposed to be a fast fight, but about two OLD friends, now enemies, going at it while talking as well. This is kind of old classic movie style, like Erroyl Flynn, like fencing, while the action is a basis for the dialouge to take place.
As for the Catina scene, also another great scene that should not be tampered with.
