Until now, I never really thought of Plo Koon as much of anything beyond a strange background character in the prequels. And, to be fair, that's all he was at the time. However, with only his first appearance in The Clone Wars, he's already one of my favorite Jedi. He has an Alec Guinness Obi-Wan-esque vibe, which is fitting considering that he's voiced by James Arnold Taylor, the same actor who voices Obi-Wan. Much as with Yoda's portrayal in "Ambush," it's nice to have an Original Trilogy-esque character in the show.
On the whole, while this episode isn't quite amazing, it's very good.
