Fantastic, Fantastic, Fantastic, Good, Crap
Oh Jed Mercurio, just when i had given up on British crime drama you came along with a clever, suspenseful mostly non-clichéd piece of work that until the last episode had brilliance written all over it.
Then you did your best to ruin it with a hurriedly written, plot hole riddled impotent final episode.
Olympic analogy: dropped the baton on the final leg and finished well behind the Americans.
