What's missing is that there's no point-of-view character, no emotional anchor.I've enjoyed series 5 & 6 but I think it's lost the spark that the RTD era had; I don't know how to describe it but it's like something's missing.
Strongly, strongly, strongly, strongly disagree.
Amy has been the clear point-of-view character since we first saw her praying to Santa Claus in "The Eleventh Hour." She's the character who introduces us to the Eleventh Doctor; she's the one who introduces us to the world of Leadworth and its community; she's the one to whom the Doctor introduces his world; she's the one whose life drives the arc of Series Five -- it was all leading up to her wedding, after all; she's the one who re-introduces us to the Doctor and River in "The Impossible Astronaut;" she's the one whose perceptions we see through Series Six (Madam Kevorian's appearances in walls); she's the one whose family life drives the Series Six arc; she's the one whose relationships bind the TARDIS crew together.
You may not like her, she may not work for you, but the show has been very clearly told from her point of view since Moffat's era began.
