Review of The Rising of the Shield Hero

First of all, I'm spanish so there may be some mistakes. And it won't be too long, I don't want to write an essay. About tate no yuusha... It started super good, was flesh air for the isekai genre, the MC is not the best and everyone loves him, as fact he's considered the worst hero and hated by everyone. Then if it's original and interesting, why did I rate it as a 5 out of 10? Because after 3 or 4 episodes where he gets the chocobo, there are only fucking side quests. Is like you're playing a game and instead of doing the main questyou start doing random things. And we have around 10 episodes of that. Half the season is useless basically. All the side characters are as dumb as Nobita. Myne is a character we have to hate but... She's not that bad. Like you can see at characters like Griffith and then she's a good person. I don't like to make comparisons but is to have and idea of how a character you should hate looks like.
And the worst part about it, it's a cliche isekai, Naofumi has his harem, he has op powers because yes, because he's the MC. They lied to us, they showed it as a original anime series that doesn't follow the same formula as the isekais, but it became one of the most boring isekais ever. And I hate it.
In short, there are 3 good episodes, a lot of filler in the middle and an epic final fight filled with asspulls and generic as hell
