The second (or third) and final season of the 2D-animated Star Wars spin-off, presented on DVD as a one-hour movie.
This season was designed specifically to tie in with the then-imminent third/sixth live-action Star Wars movie, Revenge of the Sith (which I'll be watching this weekend as part of my Star Wars re-view) -- the last episode takes place just minutes before the opening scene of Episode III, and the rest of the season details (in part) adventures alluded to in the movie.
There are pros and cons, compared to Volume One. The episodes here were three or four times as long, meaning they didn't have to focus quite so heavily on action and could dwell on character a bit more. At times that works; at others they seem to have forgotten the episodes were longer, so only afforded them the same amount of plot -- the individual action scenes just go on longer.
The Battle of Coruscant (which we see the end of in Episode III) is good, but because Anakin and Obi-Wan aren't allowed to turn up until the end, they have a subplot where they're off on some Outer Rim world saving a Native American-esque people (who also kinda look like Avatar's Na'vi) from nasty mutation. It's a bit "so what?" given everything else going on, but at least there's Mace Windu, Yoda, and some minor Jedi kicking ass on Coruscant to keep the mood up.
As with the first volume, a surprisingly-thorough episode-by-episode guide (though, when the episodes are 12-15 minutes long, it seems a bit less ridiculous) can be found on Wookieepedia
Posters for each season, which reflect Anakin's shift to the dark side.
(Wish I had them bigger/higher quality...)
