That was a startlingly intense and violent episode, and if not for Lucas's clout, there's no way it would ever have gotten onto Cartoon Network. I suppose I can respect that in principle, but it was kind of disturbing to watch at times. The shots of those poor Geonosians burning to death were very disquieting.
And I'm not sure how coherent the story was. The plan didn't seem to make a lot of sense to me. Why not use the star destroyers (or whatever those triangular ships are called in this generation) to attack the main target instead of sending in ground forces that got creamed? Why would these three different divisions have to unite in one place and make themselves sitting ducks?
And what the hell is the deal with that shield? It didn't keep people out; it didn't keep vehicles out; so what in the world was the point of it? I'm guessing it blocks laser fire, but so what? Just fly a big ship through it and start shooting. And the Jedi ran right through it with their lightsabers deployed, so I'm not even convinced it would block energy weapons (although, okay, lightsabers are supposed to be magical superweapons or something).
There were a couple of interesting bits of foreshadowing with Anakin -- his angry, petulant reaction rather than concern when Obi-Wan is shot down, and his cavalier treatment of killing as a game, casualties as mere numbers. Both signs of the foothold the dark side has in him.
Speaking of the dark side, I assume it was Palpatine/Sidious who tipped off the Geonosians about the Republic strategy. That's something he'd have to be careful not to do too often for fear of raising suspicion, though.
Then again, Yularen seemed oddly unconcerned about the danger the ground forces were in. Maybe that's just his stoic manner, but his delivery here made me wonder if maybe he could be a traitor/spy. After all, we know he's going to end up on the Death Star as a member in good standing of the Imperial military, so his loyalties are questionable. But by the same token, if he is a traitor, then either nobody ever finds out or the Republic imprisons traitors rather than executing them.
