gaggle64: Wonderful episode overall, this was great pick up from last season's rather tepid finale. I do think Moffat has lead the show into an awfully convuluted place though and we only seem to be going deeper. We need a huge reset of somekind at the end of the season, it seems like everyone has to have watched every episode twice and taken notes. It's fine for dedicated fans but I can't help feel it's probably alienating a lot of the more casual TV audience.
