I'm enjoying the series so far. Those touches of Joss Whedon humour, hints of other story lines to come, quality special effects.

The quality of the production alone is above most of the schlock available on current television. Yes there are hints of the Whedon "formula". The older mentor, the younger group, the strong minded young women. It's all there. But it's a proved winner.

Like a lot of series it needs to settle it. The actors need to settle into the roles and the series direction needs to be established. It's getting through all that, give it time, there's a great deal of potential.
