I dunno man. Can you really go back to the year 1977 and screw around with stuff and not have it stick out like a sore thumb? Sadly these changes zap you out of the movies because they just don't work. Not to get into them too much, but those two scenes really screw up the film the way they were handled. As soon as Han starts getting moved around like a digital puppet and a CGI Jabba starts running around 1977 it's like the guy next to you in the theater starts farting really bad and the smell just lingers.
