I watched it. I loved it. And I'd like to say that I wish Dave Filoni was producing the movies as well.
The protagonist, while generally stoic and badass, is not overly stoic and bad-ass, there are moments where his humanity shows through with humor, uncertainty, annoyance, and a host of other emotions not usually associated (and not easy to portray) with masked bounty hunters.
The show seems to be really promising, and the trailers absolutely did not spoil it, as most of the trailer scenes are from the very first episode. I'm eager for what's to come.
