I genuinely don't get the love for this story. It starts out very intriguing with the characters acting confused and suddenly attacking each other, but then more and more things happen and nothing gets explained properly. Why were they all acting like that?

I don't hate the resolution. I think it's cute, and I like the idea of something tiny going wrong and causing everything to spiral out of control. It makes for a great metaphor. I also like the soft moment between the Doctor and Barbara right at the end.

I guess my problem with this story is that it feels like it's having an identity crisis. It doesn't know what it wants to be or what story it's trying to tell. It's confused and all over the place and I just don't see the point of it.
