I've been rather eager to get to these episodes and was not disappointed. I will say that Mandalore does not seem anything like what is described in the LOTF series, although, of course, LOTF does take place nearly 60 years later, so a lot may have changed but I suspect that what we saw tonight was the start one HUGE re-write of the Mandalorians, their culture, etc. It will be interesting to see this further developed.
As for the characters, the Duchess seemed very Padme-like to me, which, of course, isn't a bad thing per se but just pointing out the obvious.
Obi-Wan had a lot of great scenes and lines in this episode and it's nice to see Obi-Wan on a solo mission- his first one since AOTC I believe.
The Mandalorians ("Death Watch") were as cool as ever but it's definitely interesting that the warriors were considered to basically be "rogues" and that Mandalore was (or was at least attempting to be) a more pacifist world. I wonder if the war brings some major devastation to the planet- or "Death Watch" eventually assumes power and takes Mandalore back to its more warrior-like ways?
I thought it was a nice touch for Obi-Wan to mention Jango Fett when speaking with the Prime Minister(?) of Mandalore.
Heavy subject material in this episode- bombing, suicide.
The one thing that slightly confused me was that the leader of "Death Walk" had a lightsaber that he stated that his ancestors supposedly got during the fall of the Old Republic but I thought that the current government was the "Old Republic"? Did the writers get mixed up or something?
Overall, cool episode. Can't wait until next week for the next part (this is supposed to be 3-part story arc)!
