I've gotten used to him ... but he isn't as good as Tennant. Or Eccleston. Or David Morrissey, for that matter.
Likewise, I don't like the version of River Song we get to see now. She's somewhat removed from the version in the library (even though she's older in the library).
Agreed. He even says in the last episode, “I’m married.” Show us a married doctor, living and traveling with River Song!
