That was a fun episode.
On one hand, the story wasn't completely original as it has a basic premise we've seen in many previous episodes throughout the series: Anakin, Obi Wan, Asoka, and the clones getting sent to rescue a Jedi holding some sort of valuable information we've never heard of before (but on which the whole fate of the galaxy rests) in some sort of impenetrable location. On the other hand, the episode brought in new - and old - characters and works to set up the key relationship between Anakin/Vader and Tarkin in ANH, which I liked
The whole Citadel interior really reminded me of the Death Star Detention Block from ANH more than anything else (and it was kind of fitting to see Tarkin in that setting). I kept waiting for someone to blast a hole in a wall and all our heroes go sliding into the garbage chute
Nice to see Phase II armor appearing more often on Clones as well, even now some of the main ones.
My biggest beef with the episode was the carbon freezing thing. It was just too thrown in there and too cheesy. Don't they already have scanner-proof compartments that they could hide in like on the Falcon? In ESB, Lando and even Vader expressed too much concern over the process of freezing a person in carbonite (heck, Vader didn't want Luke damaged by carbon freezing, so he tested it on Han Solo - and there was surprise that he lived) yet this episode made it seem as though the process was completely routine, harmless, normal, and that one could have a carbon freezing chamber (complete with Ugnaut) right in their own hanger. In some respects, the carbon freezing sequence in this CW episode diminishes the drama and danger of the carbon freezing scene from ESB, which was always one of the most emotionally powerful of any scene in the Star Wars saga, at least in my opinion.
I did, however, like the wisecrack about not wanting to wind up as a wall decoration
