OMGosh! I can't express, in text (but possibly in interpretive dance), how great this show is (thank you Netflix for letting westerners have access to it)!
Mystery, Comedy, Romance, Supernatural, Drama, History, Suspense...all you could want but so much more. It's addictive and well balanced. Its strangely comforting because you grow so attached to the characters. It's main story arc is often in the background to the murders the brill team solve per couple of episodes - although that makes it seem formulaic, yet its not.
The production and cinematography are high class.
I think it's the characters that I fell in love with the most. My favourite, the female protagonist, kick's ass.
I get a similar feeling when watching Dr Who or Sherlock.
If you don't mind subtitles then you'll be happy if you watch this.
