Watching this series for that reason is a real blessing. I am not joking the least, and do not think for a second that is an insult because it is actually the biggest praise I can give. For example, when I watched some highly appreciated series -- which I will not mention by names, you can find them on any top 20 anime list on the interweb basically -- many of them contained this one cliche which I absolutely hate.
Whenever a character is about to die, another character/nakama quite literally teleports there and saves the other character from certain death in the very last second. It's so f****** annoying that it kills all the believability for myself in works that were otherwise good. When Fairy Tail does this exact same thing, it is not even a flaw but a pure feature/attribute that the viewer already expects of it. For that reason, Fairy Tail does what so many other shows can only dream of: It never disappoints.
It simply can't. And that's precisely why the story is such a major success. This is one of the very few series which I can watch without asking any questions because I wholeheartedly acknowledge that there are no answers.
It may be childish and problematic, but damn if the series doesn't know what it is. What I would in other cases call 'an absolute horseshit of a writing', In Fairy Tail's case, I casually laugh and say 'oh, that's just Fairy Tail being Fairy Tail.'
In one way, this entire series is Moon Moon the meme except it's an anime: this anime. I can't hate it, it's too special and precious. Characters: Like scarce amount of shonen series -- which I will not namedrop here -- Fairy Tail does what so many others are so afraid to do: Give us canon pairings already when the series is still ongoing. 2/3 of the big 3 were nothing but a tease, the last one purely uses girls in comedic fanservice. The biggest meme, by Bones, made romantic situations a damn running gag.
