I like a mix of seriousness and whimsy/humor. All dark is not the Doctor to me. I'm looking forward to seeing what Capaldi does in the role. And River Song was awesome; if she hadn't been such an important established character, I would have LOVED for Alex Kingston to become the Doctor! Was really hoping for a female doctor this time, come on guys, mix it up a little. This is sci fi, we need to push some boundaries.
