I finally got around to watching those new episodes. While doing so, the following thought occured to me: "Wow, I can never go back to watching David Tennet as the Doctor. This new guy is just too good." I've yet to confirm this hypothesis by watching an older episode.
When I asked TCAS, all responders but 3 admitted (directly or indirectly) they had no idea what I was talking about. One of those three called him different, but good. The other 2 said he's not as good as David was.
That being said, I actually prefer the onscreen chemistry of The 11th Doctor and Amy to that of the 10th Doctor and Rose.
