“It’s so weird. It’s just so weird. I was 21 when I started this job and I didn’t really know what I was getting into. And then it just went crazy. It was this whirlwind. I’m coming out of the other end of it and I feel like a different person almost. And I just had the best time of my entire life doing this job. Honestly, I’ve got to say that. So obviously I’m going to be sad to be going and I’m going to be leaving my best mates behind. But you know, all things come to a natural end and that’s what the show’s about: Change. And you just kind of have to embrace it and go with it.”—Karen Gillan: Why She’s Leaving Doctor Who - TV Feature at IGN
He’s my favorite Doctor Who, no slight to anyone else who’s played him (not a bad one in the bunch of them - which is 11 at present count). He’s the guy who helped re-invent the franchise, making the Doctor cool and bizarre and fun again. He left after one season, not wanting to be typecast, breaking many a fan’s heart in the process.
