I think the show is really worth watching. It's short, condensed, well balanced between the self-conclusive episodes and the main plot. Nothing new, slightly flat characters, but a whole lot of entertainment.
That said, it's interesting how much derivative the show is. The locations, the iconography of the ghosts, the dynamics between ghost and characters... everything seems to convey a sense of deja-vu. And it's surprising how much this show tries NOT to be British while still remaining it; the reference is more or less the recent American horror (and, indirectly, the Japanese new wave) but many things in the production (good lookin', sexy actors; cinematography; editing, ecc...) just seem to try and be in that trend, maybe to be "easy". On the other side, a kind of British aftertaste still remains and the writing (characters issue aside) is really good.
It has it's flaws, but still works better and better each episode, till the great, though a bit "tecnical", final cliffhanger.
