Exactly!
Look at how brill it was when Christopher Eccleston became David Tennant. Yes we all knew come the end that he wouldn't filming another series, but no one had any idea who it was going to be and when DT's face appeared after the regeneration, it was like - Whoa!!!!
Now, especially for the last of the specials, well, we know that DT is going to regenerate, and we know he's going to regenerate into, so and so, the exciting edge will have gone!
And will the newbie put the same comic-ish edge on the character, or will they put a more serious one on, etc etc - I'm just finding it spoiling it a little bit tbh.
That being said - I'm still going to watch Confidential to find out who it is![]()
