I just love this show. When I watched it a couple of years ago, I just couldn't get away from it. Slightly agrees with the general consensus that the show been a little spoiled with the last seasons. It's like they've already tried to add all the wicked, evil, demons, angels and stuff they've just found on the net. And at the end, they just started to run out of ideas and it's a bit noticeable. To me, the ideal ending would be that the two brothers peacefully went into the sunset to hunt some werewolf or vampire or something.
