I still love Jar-Jar performance at the battle of Naboo. And I love Jar-Jar altogether. I mean, come on, how could you hate him? Seriously?
I like the Arena battle in AOTC, that one was cool.
Hmmm... Clone Wars cartoon... Lets see, I enjoyed Episodes 20 and 23. Those two were my favorites.
In ROTS, the space battle was cool, but it seems to get shorter and shorter each time I watch it. I guess the best part of ROTS is either the duel, seeing all those Wookiees, watching Yoda knock down the guards, Order 66, or the Battle of Utapau.
