I think Lucas is a genius. Here are some of his best ideas:
1. The Ewoks in the "Return of the Jedi" movie were awesome. Just what the series had missed. A light touch used to bring hope in this dark epic tale. And look just how superb they fit in, without a care in a world with light sabers and dark forces that blow up planets.
2. The superb new special effects which have brought the first 3 episodes (i mean 4,5,6) to the 21 century. The new backgrounds were a must and I can't even begin to praise the new aliens inside the bar, goofing around and making weird noises. And what a great idea to let the audience know that those were computer made special effects, by making them blend so poorly on the original shots.
3. Who can forget Jar Jar? The best character in Star Wars. He sits proudly as a character which has received more screen time than that so much less important Darth Vader.
4. Casting Hayden Christensen as the young Anakin, this superb actor who really made the script shine, by making Darth Vader look like a whinny prick, which we can all agree, is just how he should've been in the original episodes, instead of being portrayed by that weird James Earl dude who made him look too serious and cool for a bad guy.
