Should have ended in Season 2 Well, the writers and producers outdone themselves.
They started with a good idea, intriguing characters and an elaborate plot.
By the end of season 2 it became apparent they could not drag this anymore.
Season 3 was just a "remake" of season 1 but, my God, season 4 is an awful soap opera...seems almost like a "filler" season...no actual plot, no actual action...you could skip straight to episode 7 if u want and still..you wouldnt miss a thing.
Hire better writers, because this cast is impeccable.
