Yeah, I thought Eccleston done a good job too and I was pretty peeved he quit because I thought all the good work would be for nothing and the series would die, but it looks like they are making the most of Eccleston's departure by playing on the fact that he looks different and nobody recognises him, until he gets down to business and his actions show that he is definietly the doctor.
P.S Jason, can't reply to PMs, but I don't actually have Rikter's postal address. You need to talk to PSYCHO_DAYV.
