The shoddiness of Han stepping over Jabba's tail still cracks me up. It looks like he's riding an escalator.
Im very late to this party, but i agree, i hate the way this was done, im sure Lucas couldve been a little more imaginative and left han just walking around Jabba normally, Jabba couldve moved with him kind of keeping eye contact and swivelling his tail. It just looks dodgy.
Not too mention, somehow Boba fett has his ROTJ armor and ROTJ rifle.
