I love it!
but there's something about the doctors dialogue that just seems...off. I'm not sure if it's the voice acting, or the actually words he's saying, but it doesn't seem quite right. It might be how in the show, he usually quips a lot of jargon quickly to himself before breaking it down into laymen's terms (see 'wibbly wobbly timey wimey...stuff')
I guess what I'm trying to say is that the dialogue seems to over stress how smart he is, rather than trying to be the charming, if slightly mad, kind of person he is portrayed as in the show.
