It has all of the characteristics of Prison Break flight of icarus path - high on mystery and secrecy start, short bursts of conspiratorial arc and then, as the season order is extended it immediately melts down to per-episode-short-arc season survival filler, but this time it's the dreaded round the mill procedural+magical sidekick we are all so sick of.
Once you start yawning at the long chain of filler episodes you realise it is nothing more than tv show by numbers - the "what am I doing here" centrepiece, the detective, the boss/director, the helping detective to run all the mundane errands in the background, the high tech "enhance" geek/engineer (now almost always a chick), the scientist/doctor/psychologist to explain things to slow viewer, the external contractor/taskforce agent/temporary assignment/out of the box person. It's essentially the standard CSI/NCIS crew plus magical sidekick. The only difference to Bones, Blacklist or endless list of the shows using this setup is the girl with the dragon tattoo.
And as the entire series is hanging on a single "fit chick" doing the same one trick pony teary eye misery-written-all-over-her-face high strung performance every week the sad truth is, as the previous poster said, the entire supporting cast is just dire, hard to watch and you kind of want them dead.
