snappy one-liners, some unusually good acting from Gillan, moving use of young Amelia, evil cherubs, nice use of Doctor's awkward preening.
poor plotting, clumsy direction at key moments (e.g. Rory and tombstone), ham-fisted characterisation in parts (e.g. Doctor as one-dimensional needy loner).
Statue of Liberty (i.e. implausible and very badly executed), very rushed (a Moffat trademark).
Nothing in this to rival Ten and Rose or Donna (for very different reasons, obviously). And not a hint of the authoritative madness of Four.
This is all a more dispassionate assessment. When I suspend my disbelief, I still enjoy it. Even when mediocre, Doctor Who combines the silly and somber, irreverent and dignified, in interesting ways.
