I liked very much these episodes: they are exciting like the first series but they have the peculiarity of linking the series, and Episode II, with the beginning of Episode III.

They also introduce us to Episode III characters like Grievous(who has here more space than in the first volume) and his Droid Bodyguards, to ROTS new vehicles like Republic Star Destroyer, Separatist Cruiser and Droid Tri-Fighters; and even to Episode III events like the Battle of Kashyyk!.
I'm very happy they made a series like this.
