Oooof. This was bad. I don't care for the scooby doo gang, and even though I love Doctor Who I was almost to the point of turning it off until The Doctor showed up. Then I hung in but it was still as uninteresting and unfunny as the beginning...just with the Doctor.
The Tom Tom joke? Uh, ok. Ha?
Strax being Strax? Completely over it.
This ep basically boiled down to "hey a random creature made a person evil. The Doctor stopped her." We've seen that a million times before, and it can be good but when you add in the awful "comedy" and focus on the scooby doo gang...it's not for me.
So far this season, I would say I enjoyed Hide, but I can't even remember what it was about. The sub one was eh, and the Dalek one was the last one I remember liking, but that was forever and a companion ago.
Moffat needs to go asap. And I don't think Gatis is the answer at all.
Did enjoy the flashback immensely however.
