I tend to agree with you on this. I have a problem with Eleven's lack of gravitas, which was never missing from Nine and Ten, but a lot of that can be chalked up to the scripts. I summed up my feelings about Eleven in a conversation the other day: Most of the Doctors are trying to save people. Eleven tries to look clever. Saving people -- optional.

I'm also extremely unfond of Moffat's predilection towards embarrassment humor. Just too many times, the Doctor or Amy or Rory has spent a minute or two looking like an ass and knowing it (maybe not in the case of the Doctor, but we know he looks like an ass and we have to suffer for him). And the Doctor just says random shit that somebody working on the script thought was clever. It almost never is.
