after 2 seasons, this feels like the worst UK detective drama I've ever seen. but it was created in 2011, so maybe it worked well then, case/investigation-wise, but the characters were shitty even then. season 3, is even worse. they just make others suffer, in personal life & in professional lives. and everyone else gets punished for it but never them. had it been some gangsta stuff or some misguided loyalties, I'd have understood them but this is...i just can't sympathize with them. don't know what the writer thought they were doing with character development, it has made it worse to watch. season 4, continues with the trend to promote these ladies who aren't really that brilliant compared to others & keeps firing others for little mistakes.
