Fairy Tail's Last Arc should have been the best of all arc. But it's not. In this Arc, there are many characters. They introduced the spriggan 12 and said that each of them has strength similar to GOD SERENA. Zeref said he will put Natsu in bigger despair. But there was no despair or too much of a hurdle.
Characters-
Unlike Naruto or One Piece, Fairy Tail's each and every characters are invincible. They do not die in the hands of 10 times stronger enemies. Enemy characters are given overwhelming magic power without any talent on how to use it including ACNOLOGIA. There were some characters who didn't notice enough attention like GOD SERENA.
Sound-
Soundtracks are nice but sometimes voice actors voices just don't match the situation. Other than that, everything is fine.
Enjoyment-
Not enjoyable as the fighting moments are boring. The animation is very slow and sluggish.
