I thought the storyline in The Haunting of Villa Diodati was very good. At least until the very end with the Cyberium. Before that both Praxeus and Can You Hear Me? started off well before going downhill. Definitely steps in the right direction. Ascension of the Cyberman had a bit of a retro feel to it, like they were remaking a Davison era episode. Nice to see the 80s style cyberheads again. It was marred by the whole flying the cybership nonsense though... but I guess you can't have everything. This series is a definitely improvement on the last, despite not being as good as anything that came before S11.
