I didn't care for this one very much, the Doctor/Matt felt forced when he wasn't just simply out-of-character. Hell, he basically got the one truly good man killed by throwing a tantrum.
Why'd he ever drop Amy and Rory off in the first place? Seems pointless if he's constantly going on adventures with them. I know the whole codependency or whatever thing is coming up but it just doesn't feel right.
I think the horse gag would've worked better if he had stopped with the first line.
Next week looks to have potential to be interesting.
