Bingowings, some nice ideas there. Seeing the AT-AT in the forest would be awesome if it could be worked in.
I watched the 2nd half of Jedi last weekend, and one thing that struck me during the Ewok battle was the lack of laser blasts. Especially in the scene where the Ewoks first surround the stormtroopers and attack. There are arrows flying everywhere, but the stormtroopers only squeeze off a few rounds. If anything can jazz up the battle a little bit, it's hundreds of laser blasts!
And earlier, when Teebo steals the speeder bike and leads away all but one scout from the bunker, we shouldn't need to see what happens to him. As a virtual nobody in the movie, he really doesn't need his own personalized chase scene. Better yet, you could save his antics for later during the ground battle, where he leads the 2 scout troopers on a wild goose chase - he ditches, and then the scouts get taken out by the ewoks waiting with the throat-rope.
Jedi Rocks should be removed in its entirety. It's AWFUL. The song is awful, and the new CG is the one reason that I flat-out refuse to put the SE in my DVD player (for me it's worse than Greedo shooting first). Lapti Nek is much more fitting, although I'd be perfectly happy if the musical number were cut completely.
(It's strange how the humor added to ROTJ seems to parallel the humor in the Last Crusade, especially in the Harrison Ford department. You know, it's like they're trying TOO HARD to be cute and funny. I guess that's the only kind of trilogy-ender that George can cook up. Man, I almost wish Adywan would skip ESB and get right to ROTJ.)
