@boomloverIdk. I liked the first season since the concept was really interesting and sadly...I am a sucker for romance.
The second season sucked. It was just horrible. Yes, I am a lover of fantasy and that was a neat point even though plot was pathetic and just blah
The third season was pretty epic for the first half and was more action packed which was exciting and then well the second half of that second was just boring with no real point. It didn't even seem to follow a straight timeline.
As I said, the manga was better than the anime sadly. I just found that some parts were really good but it isn't top on my list because some of the negative aspects.
