^If that's the case, then I believe they spent lots of money for something that looked and felt like what RTD did for much less. As a producer of "The Bells of St. John", I would find that pretty embarrassing. It's the definition of waste.
Maybe there weren't a ton of big effects sequences, but the episode still looked MUCH more stylish and expensive than anything in the RTD era.
Especially in the outdoor scenes, where it looked more like an episode of Sherlock, or one of the sleek and modern looking Bourne movies.
