I enjoyed last night, especially the music, which evoked James Horner's Star Trek scores, right down to the virtual echo of the Klingon theme toward the end. I loved the submarine vibe, too, even though the strategy involved in the entire thing was as sound as the rest of the series.
I disagree with the Mandalores being the low point of the year. I see that arc as the high point, tied with Geonosis. I'm not a EU guy, so I don't have any preconceptions going in to color the Mandos, and the character building with Obi and Satine was for the series, superb.
I think the Bounty Hunter thing was oversold, too, but I don't particularly mind. The season has been somewhat uneven, due in part to its schedule, but overall it's much more solid than last year in every way.
