I thought the alien from the planet that always surrenders was pretty interesting and funny. Their planet's national anthem is 'Glory to *insert name here*' haha!
I would have loved to know Rory's fear. (It was still their fears in the rooms, right? Even though the monster fed on people's loss of faith/conversion to worship it). And the Doctor's fear too. I laughed when his room was number 11, how cliche of the writer. I know he did go in and say "of course, who else?" but who could he be talking about? I'm thinking Rassilon and the timelords in general because last time they were unleashed things didn't go too well. Maybe River (if it is her in the astronaut suit) or himself? These are just my silly theories though, who do you think he was talking about?
I think the concept itself was interesting but I'm not very good at being analytical and all, so I won't even bother trying. Although, I always love when the monster really isn't a monster at all, just sort of misunderstood (like Frankenstien's monster. Best book I've ever been assigned for school)
Also, I wonder what was with the exit door that Rory saw and then just disappeared. Was that of any significance or am I just thinking too much about things?
One last thing, the ending was annoying. I love Rory way too much. I don't want to see them go. Especially how they were just kind of dropped off, after a cab ride (which is how I think Amy put it). I know they will obviously be back but still.
I am excited for Craig to be back in next weeks episode though! Let's hope we see some more of the Doctor's soccer skills ;)
