Are you seriously trying to compare "Dinosaurs on a Spaceship" with "Blackwater"? Sure, Doctor Who is a great show, but it's a silly adventure series. It's not epic. With Game of Thrones each episodes feels like an event which means you don't feel ripped off for only getting 10 episodes a season.
Nope but I did see these silly epics called The Avengers and The Hobbit without feeling ripped off, Dinosaurs on a Spaceship is quite similar.
It's funny how much more Hollywood manages to spend on products not much better than ones at a fraction of the cost. Tv can't afford millions of orcs but a million daleks serves almost the same function.
