Ambush: Everything that needs to be said has already been. Awesome to see Original Trilogy style Yoda along with the Zen aspects of the force. The SuperBattleDroids finally have voices and the lightsaber rotoscoping effects were standout.
Another interesting aspect is of course
The Phantom Menace influence over the episode. From the obvious Toydian presence to the Trade Federation BattleShip to even the music. One thing I would like to seen is a more formidable Ventress when she faced Yoda at the end.
Rising Malevolence: The Grievous BattleShip was one of the leaked "DarthFriday" concept images from back around this time in 2003 and it was nicknamed the Shark Ship then. The craft was dropped from
Revenge Of The Sith but reappeared in this years Clone Wars. The huge steamship style "paddle wheel" is actually the energy-disableing Ion Cannon. whoa!
Another concept that was lifted from
Revenge Of The Sith was the whole falling out of the ship into zero-gravity space sequence(s). Speaking of which the BattleDroids get some kills under their belt using this method. The episode sorta has creepy vibe because of the energy zapping weapon shutting down ship's power and clone death by space suffocation methinks - very eerie.
Stand out performances were of course Plo "Plo Kool" Koon and the Clone Troopers. Plo got to put his breath appartus to work. It was interesting to see Fett Clones as Imperial Officers and the introduction of some sort of Space Trooper. Grievous gets a nod for best supporting performance.
A weak point and I hate to pile on here was the Anakin and Ahsoka banter - although it was drowned by the overall awesomeness of the episode. The BattleDroid banter in both episodes was actually sort of cool. In
Rising Malevolence, after one of the successful kills, one of the BattleDroids started humming a tune on the way to killing their next set of Clones.
