I didn't get to watch last week or this week's episodes until Saturday night and I have the same "meh" reaction. It was certainly better than watching Dora the Explorer, but sub-par for the Clone Wars. Two things to comment on really though:
First, why did Lucas mess with Mandalore? I've read all of Karen Traviss' books and think that the backstory she developed fit better with the other EU. (Isn't that a bit of circular logic on my part?) Plus, it could have fit within the story that the Clone Wars was telling (the hiring of mercenaries/bounty hunters to train the clones, clones being individuals with varying motivations, etc.). I think that most of the story that has taken place on Mandalore could have easily been transposed to nearly any other system; which would have left intact the Traviss story.
Second, I'm hoping there is a big pay off to the Mandalore episodes. Dutchess Satine needs to do something big. Unless she's been manipulating everything to take out her political opposition and cement power for herself so she can join the Separatists (perhaps Obi-Wan could be torn between what he has to do to defend the Republic and not wanting to fight against Satine, who he loves; but NOT as a brother..), I'm going to be disappointed.
To me, and clearly most of the older viewers of TCW, the Mandalorian episodes are largely a diversion from most other episodes. So without a reason to focus on mandalore (aside from selling Pre Viszla figures), I don't see a lot of point in Lucas messing with what was a fairly well fleshed out area of EU.
