Mini-review of Doctor Who season finale

Um, yes, I've not been doing well with regular reviewing, have I? I blame the uncertainty of my computer, which now seems to be having more Mcafee issues (argh) and may also be having some problems with the connection to an external monitor. I'm typing this on the family computer because I couldn't face the thought of trying to bully my laptop into behaving today.

Anyway.
