I think the scene should be left out because of the crapitude of staging a scene around a CG Jabba. For whatever reason, Lucas can't simply cut away to something, he has to make Han step on Jabba's tail.

Basically, Han is at Jabba's mercy. Jabba has a crew of bounty hunters with him, any of whom, I'd imagine, would be perfectly willing to blow Han away if Jabba gives the order. Stepping on Jabba's tail isn't what any thinking person would do in such a situation.

But there's also the CG itself to think about. It played in TPM because Jabba was only in, what, two or three shots? Plus, he needed to move around a little bit. No big deal. But he's the focal point of the hangar scene and the aesthetic differences between even the 2004 CG Jabba vs. the 1983 puppet are too vast to really believe in.

ANH was fine the way it was, it doesn't need a bunch of CGI and crap like that. The Jabba scene should be cut back out.
