Yes, there tends to be a lot of nuttiness immediately there's a new Doctor, but sometimes that nuttiness sticks around, so you can never be sure that things will calm down. If he stayed as bonkers as last week I'd've had a fight between the urge to stop watching him and the urge to keep watching Amy. At the moment I'm definitely staying on the side of continuing to watch. Also waiting for an episode of the calibre of the ones Moffat has written before.
