One of the series hit extremely hard by the writers’ strike. I would assume that the arc storyline would have been told much more smoothly and progressively, instead of having the sudden reveal in the final episode which came completely out of nowhere and was not only poor storytelling, but almost offensive to the fans who deserved better.
So the series was spoilt by things that weren’t there, but what was there was entertaining and mostly unremarkable. The new character of Dr Sweets is interesting and fun, but a bit gimmicky. I think they tried to be big this year with the arc, but weren’t quite up to it with the added complications of the writers’ strike.
