Well I ended up watching it three times, one of the times a fell asleep.It was pretty much a 'nothing' episode. Nothing really happened, nothing was gained from this episode and we learnt pretty much nothing about the characters. *yawn*
Plus it was a cheesy, fanwanky, mess of an episode. Seriously? The Tardis inhabits a lady! Ooo!!! Fan-fucking-tastic. It's the sort of thing a nine year old with dementia would come up with. Almost as bad as 'Fear her' or 'Love and Monsters'
You must have been watching something else and not "The Doctor's Wife". We learn TONS about the Doctor and TONS about what we always speculated about, that the TARDIS was sentient. We learned that one of Amy's fears is how Rory feels about her being away for long proofs of time, and that Rory remembers (and feels) the 2000 years he waited.
Maybe you watched last weeks episode by mistake. It was a fun pirate romp, but no character development.
Seriously? Is this this what passes for Doctor Who these days? Goddamn!
