You won't be disappointed - Tennant's Doctor is similar and yet very much different. ALTHOUGH what I am trying to figure out - watching Series 1 all over again today hehe - does Ecclestein ever change his shirt? LOL It seems like he's wearing the same thing every single episode - at least Tennant switches off now and again.
Hah the real reason why he left Who - "Wot? You mean I COULD have changed clothes more than once? Bloody 'ell! And the new guy gets HOW many changes of clothes? You pissahs."
