The first two seasons were amazing. Wonderful supernatural stuff with excellent story. Rest of the seasons are divided into two parts. The first half of season 3 was good although not as much as 1 & 2. The rest were so poor nothing happened made even a bit of sense. They went way too much with the supernatural thing. They brought in so much magical and unbelievably incredulous stuff nothing made sense, it felt like they just wanted to take the show ahead not caring much the way they are taking it. Banshee, Kitsune, Most of the new antagonists which I wouldn't like to name to spoil the things, were simply horrifically unreal, although werewolves aren't either but NONE OF THEM MADE SENSE. The moment Kira entered and the Japanese demons took over, nothing was as before. Should watch only first 2 seasons, rest you might like too, but wouldn't understand for sure.
