Some people think that Fairy Tail is a bad anime. Supposedly because the story is bad.
Now I'm not one to deny that, but you don't watch Fairy Tail for the story. You watch it for the characters and for its meaning and message. In my rewatch, I'm noticing anew just how much Fairy Tail agitates against an individualist notion of strength. Also, the emphasis on restorative justice rather than punitive justice (not perfectly done, but still pretty good).
