A considerable part of the charm of Doctor Who for me is its ability to shift between a variety of genres (SF, fantasy, gothic) whilst, plot-wise, basically remaining a family adventure series.

I admit I'm not a great fan of complex arcs and would prefer strong and distinctive stories-of-the-week. Having said that, the fairy tale flavour of last season worked particularly well for me, and I've enjoyed this season's nods to Indiana Jones.
