I didn't have much of a reaction either way to this EP. It didn't strike me as particularly good or bad, just sort of filler.
Dooku makes me laugh. You're trying to secure information that could turn the tide of the war, and you entrust the whole operation to a bunch of droids and that goofy ass warden? Damn right that needs your personal attention.
They'd be better off just nuking the planet from orbit to insure that the Republic never got that information either.
Lots of good toy fodder from this arc though, would love some animated probe droids and those commando battle droids with the shields.
The Citdel would make for a hella cool playset too.
