I've never particularly disliked Jedi, and the dogfighting at the end rates above the RoTS opening sequence if you ask me. I totally dig the little furry guys defeating an entire legion of Palp's best troops, though it is best not to overanalyse the whole situation.

The Ewoks only got annoying with the release of Caravan of Courage and that other movie which mercifully eludes me right now. They became oversaturated on TV thanks to the cartoons and plush ads (remembering that back in the day the UK had like 4 or 5 TV channels)
