Hey, what do you know? That didn't suck. It wasn't groundbreaking, it didn't reinvent the wheel, but it was competent. The Doctor got to do stuff! Not as much as in some stories because of the huge crowd of characters that had to be serviced, but actual stuff. And we didn't just run away at the end!
It wasn't great Doctor Who. But I wasn't bored, the characters all got at least one moment and the guest cast actually did a really nice job this week. So it was at least decent Doctor Who.
I was somewhat taken out of the episode by the overwhelming similarity to the Racnoss. But maybe that was intentional and just not played upon. But even the queen felt like a really similar design, right down to the head "crown" and the teeth. (Though, to be fair, I'm saying that from memory. I haven't watched the Racnoss story in ages, so maybe it isn't as similar as I'm recalling.)
Better. That's not saying much, as last week was a complete flop, but better. I could be ok with this level of quality if it's the best we can manage.
