DT was the best Doctor since Tom Baker.
I seem to recall reading that Tom Baker hailed DT as the best Doctor ever. (and he was right)
Having said that, I was incredibly impressed with Eccleston when he revived the series. I thought, "Yay! Dr Who is back!" quickly followed by, "this guy is fantastic!", then Tennant just blew him away. Maybe the next doctor will do the same to Tennant.
Yeah... I know, not very likely, but hope springs eternal.
I hope that the next Dr at least does the series credit. The writing lately has been superlative and there's still a lot of story threads hanging loose so it would be a shame for a poor casting choice to let the show down at this point.
Yes, I'm still waiting (speculatively) for the return of the time lords, Gallifrey and Romana.
