It's a very simple Story, probably the most typical Doctor Who Story of this entire Collection, if I am being honest, but it still quite an effective one. While, I wish certain Things were fleshed out a bit more, in particular in regard to the Meep or even the Wrath Warriors, I do think what you have is a lot of fun. Sharon is solid, it's probably her best Story of this entire Collection. As it is, it's very fun, but gets hold back by certain weird decisions.
