Wheee-WHO! I liked that season ender. I didn't think it would be nearly as good as it was. And I still want to be River Song when I grow up, though I'd prefer the 10th to the 11th Doctor to travel with
I loved Tennant a lot, but I also loved Amy and I don't think Amy/Rory could have happened with the tenth doctor. I don't think he could have watched her be with someone else the way the eleventh doctor did, given that he'd already lost Rose too. The tenth doctor would've ended up alone...maybe that's how they end each doctor's term, once they'd be left alone it's time for a new guy.
I want to see someone a bit different for 12. Mean, moody, darker maybe. 9th, 10th and 11th have all been extremely likeable(9th&11th were growers, imho). Especially given that during the 11th doctor's time, he's become a bit more self aware, it seems time for a bit more introspection? I dunno though, camp and hyper seems to be the theme, but I don't think they can take that much further. A non-human companion would be interesting too, but probably less workable.
Admittedly, I also want to see mean and moody for my own personal gratification, but stillllllll.
'The God Complex' is my favourite of this series, mainly for this quote:
"I took you with me because I was vain. Because I wanted to be adored."
ahh, I died a little inside. If it'd been Tennant delivering those lines, I'd have cried xD
