I didn't love Eccleston either, but I just feel like he gets a lot of hate... and he wasn't terrible, IMO. and Smith has grown on me but who could ever be better than Tennant? the man was genius. that wink/grin combo, plus the chucks, and all the dashing about... seriously. although I have gotten used to Smith and his giraffe neck, I'll always be a Rose and Ten fan I am dying to know who is taking over though- my daughter is holding out for Benedict Cumberbach.
I have no complaints about Tennant. I just have grown more attached to Smith. As Vector Viking mentioned, Karen Gillan is a big part of it. (And I'm really engjoying Coleman as well.)
Are we sure that Matt Smith is actually leaving? He's signed on for Season Eight as far as I know.
I think he had originally intended to leave after this season but agreed to stay through the next. And I loved the character of Amy Pond initially but I got kind of tired of Amy and Rory, and then completely thrown by the whole Melody/River thing. but I really, really like Clara/Oswin. she's delightful.
