I understand how you could feel that way but from my own subjective sense of aesthetics, I believe that when you do something like that, spend a lot of time on the ambiance and "feel" of a show, it should relate to something grander and more profound. Otherwise, it ends up coming across as self indulgent.
I'll give two examples of what I mean, each on opposite ends of the spectrum. The first is Rectify, which milks ambiance for every last little titty twister they can throw in. And I love that show. Part of the reason is how they do it and honestly, I don't have the skills at this point to explain what makes their execution so different. But one thing I can point to is the fact that the soul consuming desperation, hopelessness and general sense of ennui is necessary to really communicate the main character's view of the world.
He's like the rat that, no matter which lever he pulls or side of the cage he cowers in, he knows that he's going to get a shock. And this creates a pervasive sense of helplessness that inevitably leads to his not caring about anything or anyone. Except unlike the rat, he somehow finds hope in the midst of his suffering.
On the other end of the spectrum you have something like
Low Winter Sun which was canceled after one fairly short season. Now mind you, I could have watched 10 seasons of that shit, no problem, just because I loved the psychological pain, the sense of despair, the seemingly endless barren desolation. Different strokes . . . as they say.
But if I'm going to be honest, the subject matter didn't warrant such depth and introspection. It was incredibly well done and I could have wallowed in it for years, but it came off feeling self indulgent rather than profound.
I think BCS is somewhere in between. Sure, we're looking at the transformation of someone from one persona to another, at least on the surface. And they do a good job of capturing the visual analog of that transformation. But the ponderous approach doesn't seem justified by the subject matter.
