I mean the first movie had Jar-Jar, who could annoy planets to death, so what's the difference?
I prefer to think he is ultimate Sith lord
YES. Oh man that is perhaps the only conspiracy theory I buy into. It just makes too much sense on all levels. The parallels with Yoda, the drunken boxing fighting style, the randomness of the arrival of Count Dooku (sp?), some of the specific scenes where he moves impossibly fast and it doesn't seem to be a continuity error because of where the enemy soldiers are looking and firing... and on and on. How instrumental he was regarding Palpatine's rise. Various things Lucas said over the years in an indirect fashion.
It also really makes sense that Lucas would back down from having him be the ultimate Sith lord after he was so hated. I mean, I can see the logic there. That would have been a big turnaround, though, in my opinion: if Jar Jar suddenly did his voice differently like the difference between "early Kermit Yoda" when Luke first meets him, versus how he speaks later on when he's acting as a Jedi master.
Talk about a missed opportunity. But I am glad we have Snoke instead of Darth Jar Jar... I think. Verdict is still out on that one.
