The Jedi in the PT are just like the rebels in the OT. They're the good guys. You're supposed to like them and be rooting for them no matter what happens. I wasn't rooting for the Jedi cuz they weren't really all that likeable. Mace was an asshole, pretty much from the beginning. They all came off as high-fallutin', self-righteous jerkoffs who thought they were the shit.....that's not really how you would preceive the guardians of peace and justice in the galaxy to be. The rebels were likeable. There was the pilots in the Death Star attack and Rogue Squadron, General Madine and Mon Mothma...even General Reiken made more of an impression than any of the Jedi.
Take all their dialogue and put it against the Jedi's dialogue in the prequels and see how it measures up. The Jedi dialogue is throwaway dialogue...nothing really noteworthy. Hard for me to care if they aren't endearing at all.
