Have to agree with all your points there Eph, well said.
I think Yoda was about 900 and something in the original trilogy and since 2 was set about 20 years before that, well he's probably still about 900 and something years old.
Got a bit confused at the end... who was the good guys and who was bad? Worked it out eventually, the soon-to-be-emperor (if you don't know who this is yet, open your eyes

) - was in charge of
both sides and is trying to play them off against each other... sneaky bugger... it sets it up as very interesting for episode 3 anyway.
