It had an OK first season, although it kind of seemed stuck between absurdity of the concept and surprisingly serious tone it tried to struck sometimes, but all that awkwardness is gone in second season.

It kicks ass from the beginning to the end, no saggy parts. It's fun, surprisingly smart, intriguing. Everything is at amazing level - cinematography, directing, acting... In fact, it seems everyone had a good time making it and that good time translates to the viewer as well.

If you're perhaps wondering should you watch second season even though it was canceled - the main plot of the season is wrapped up. There's hints to where the plot will go next (and I really hope we will get to see it as it promises to transform the show completely yet again), but it's not a cliffhanger that will make you mad for wasting time on a show. And when the season is as good as it is, I'd say it's well worth your time.
