I agree that the absolute best Who episodes are generally the standalone ones be it The Empty Child, Blink or Forest of the Dead (all written by Moffat I know... but they are generally regarded as some of the best episodes and favourites of mine). The ones in S11 just feel quite bland in general. The episode 'It takes you away' faired the best for me... it was the one episode that managed to establish a decent mystery, sufficient tension and some sort of character/relationship development.
Most of the other episodes played it too safe, cliched and predictable.
just from Ivu; they showed the first series in May and have done nought since. kinda of sad I thought they were going to do a full rerun but nothing... hoping they will do something before the next new series with Jodie.
