Jar Jar appears in a couple of scenes but doesn't speak.
Greivous wasn't nearly as threatening as he should have been. The 'most feared Jedi killer in the galaxy' has a brief fight with Obi Wan before meeting a humiliating demise.
The film was brutally edited in parts; there'll be a wealth of material left over for the DVD.
Portman and Christensen's acting hasn't improved; sure, they're working with a dud script, but their performances are more wooden than the Amazonian Rainforest.
You'd be hard pressed to find Anakin remotely scary. Most laughable of all was his's main reason for turning to the Dark Side; to 'save' Padme. After having wiped out every person in the Jedi Temple, he's back in her arms, talking of his love for her. What a joke!
