I think Fairy Tail deserves a 10/10. I believe this because to me, it's great all around. I love the story arks, the characters personalities, the ending songs, the opening songs, and the art.
Even though I'm not the biggest fan of the most recent story ark, I understand that they have to have something to show us while the manga gets further in the story line. Hell, the way I see it is that it will give me more time to get excited when the anime finally does get back on track ! I'd rather have something new in Fairy Tail then nothing at all! I'm really looking forward to the Grand Magic Tournament!
