RTD kept churning out the same old monsters again and again, and David Tennant both IRL and as the doctor got properly annoying (much like Michael McIntyre when he realised he was famous). Chris Ecclestone had the proper kinda tough-guy capability, but DT was good for about 5 minutes, and there wasa just too much soft crap and camp-ness from RTD. He pulled shit out like blowing up the universe with a giant bomb perpetrated by a species that takes joy in each murder. Moffat, in fairness, tried to wipe the universe, but that wasn't someone being retardedly evil, it was someone making a mistake, and people having to deal with it. The big climax with Moffat doesn't have to be the ultimate apocalypse, and the episodes don't just have to be about rampaging monsters. Every episode seemed to drag down with Tennant into fan service and boredom. Aside from the Ecclestone run, Moffatt and Smith have made it a lot better, and it's more watchable than ever. The best thing that RTD did was cast John Simm as The Master: Simm's a good actor and not an annoyingly smug git like Tennant became. And don't get me started on Rose Tyler... she was ok to begin with, but... How could she earn twice as much per episode than the actor playing The Doctor, who was an established actor before landing the role?
