This show really has gone down the gutter. It really is terrible, were it not for it's tremendous atmospheric quality. Every season you know nothing of major importance will happen, except for the finale, thus you wait and wait for the main villain killer to be killed, but then you realize it will only happen in the finale, and so the rest becomes an exercise of predictability leading down to the final moment, where the reset button is pushed so that a next season may continue with the same story arch and structure, and the creators can laugh themselves silly on the way to the bank.
