So I enjoyed this week's episode a lot as well... I wouldn't say it's my favorite, but it was good. I enjoyed last week's a bit more I think, but mostly because it was more combat/military oriented whereas this episode seemed almost like a horror movie! Grievious' house of horrors basically.
I was talking with a buddy of mine who is just now getting into watching the series, and he loved the last couple episodes. I told him they're not all perfect but the last two weeks were pretty close. He digs the humor from various characters like Grievous' medical droid. I told him Anakin's droid/holo are pretty entertaining as well, mostly due to the sort of slow voice.
Anyway this past week was awesome due to Grievous' home being this shrouded fortress nobody knows or knew about. Then inside he's got beasties for pets, and lots of traps, and his guards and some droids... Very cool. I also liked Grievous' disgust at the use of battledroids, and how his relationship with the Separatists is strained (at best). It's funny how Grievous almost is pitiable, in that he'd be a good leader but he's warped now and so he's with the wrong side. It almost makes you wonder if the Republic had gotten to him before the Seps, would he be happier commanding Clones? He's clearly not happy with sub-par soldiers the Seps give him.
It's a very interesting series I think, mostly because of these little questions and details they slip in there.
Last week's episode was similarly good, but like I said it had a more military touch to it, and I liked that a lot... The boarding craft the Seps use are incredibly cool to me, and I thought the Senate commandoes were quite cool. My buddy and I are noticing the trend though where new characters last about as long as red shirts on Star Trek. Argyus, Grievous' Droid Doctor, R3S6, Trandoshan Scavenger... Lots of people getting offed. I love that the show gets a violence rating, haha. Ya know they're aiming for our attention spans by making it something more than the cutesy Jar Jar episode.
