I just came back from Ep3 yesterday, and it was very enjoyable. And Natalie Portman acted wonderfully too.
I didn't like the fact that the battle between Obi-wan and Anakin was done using 2 *blue* lightsabers. The Palpatine and Yoda grudgematch was more pleasing to the eye due to the colour contrast.
Yeah, I'm a little strange that way...
