The only objective criticism you said was that the animation was bad. Which I can agree with. But you didn't really objectively explain why it's bad.
For example...Why I quit fairy tale the manga. Spoilers: They kept introducing villains, hyping them up to be really strong but in the end defeating them because of some supposed power of emotion. I quit the damn manga when I realized it was going no where special. The entire guild got attacked by a spell. The whole world assumed them dead for years characters that knew them aged, but then they reappear exactly the same...frozen in time I guess. I thought the writers could have really done something unique there....but they played it safe. So after that anticipation I wasn't about to continue with the same cycle again. Nothing special to see there. Also none of the characters had any real character development that was interesting enough to keep me interested.
And from what i just read, there's nothing bad there because it's a SHOUNEN ANIME and almost all of them are really simple. Most play it safe too, safer than Fairy Tail. Hell it felt like i read every mainstream anime to date in that description.
Yet Fairy Tail is godlike, for what it is. To me it sounds like you're expecting a deeper thought provoking story from a show like this and that's where you're wrong.
Not to mention it was totally obvious that when the island disappeared they were gonna return the same, what else was gonna happen? It's FAIRY TAIL ISLAND, home of miracles and uber magic badassery with a guardian watching over them. Dang that sure doesn't sound like a safe house to me.
For SHITRUTO GAYPUUDAN, first off this is ANIME only, because i only talk about anime because i don't care about manga at all. ANIME, it's ANIMATION. If and when the animation and/or art work is sub par, or like Naruto here, TOTAL ASS than your show is bad. No ifs/ands/or buts about it. It's more so when you have a major god damn franchise like Naruto, no excuses. This was far actual story plots too. I can understand skimping down on a few filler eps or maybe an episode with mostly talking, but nooooooooooooooooo Naruto does it well over half the show.
And for the rest of it i'm not going to keep saying why Gayruto Poopuudan is bad. I've been saying it since 2007 on 30 different forums. If you want to know fucking google ANIMEFREAK6969, OR ANIMEFREAK OR IWATCH2MUCHANIME OR IW2MA and find it yourself.
