Peter Capaldi was in both Doctor Who and Torchwood as other characters before playing the Doctor. But he left a lasting impression as the Doctor for me.:)

I think the majority would say Ten's regeneration scene went on for far too long. He really needed Donna to keep him from going "Dark Doctor".:(

I hated how dismissive Ten was over seeing Jack again. Well at least Jack got his own spinoff with Torchwood.

That was Gwen for you. A bad observer despite being trained as a policewoman. She wanted to make Jack jealous of her with Rhys but had an affair with Owen because Jack wouldn't commit to her. I'd rather had seen more of Tosh's story arc. One flashback wasn't enough.*annoyed*
