Loved the whole premise of the show and the way it continually wrapped around itself, the final season wasn't up to scratch but it did supply a satisfactory conclusion to the whole thing, something that's rare nowadays with TV shows being binned rather than finished
Good show with some brilliant storylines, I've been watching it on and off since it started, sometimes binge watching whole seasons in a couple of weekends and sometimes not watching an episode for months, still keeps me coming back to watch it
