Sure, it is heavily exaggerated, but not wrong.
-The world is huge, yet it feels like you get a korok seed or a shrine most of the time as a reward which is repetitive, uncreative and makes exploration significantly less fun (atleast for me). It doesn't help that the shrines all have the same design. Seriously, you can count the exceptions of substantial rewards with one hand which is just sad for an exploration driven game.
- the bosses all look the same too which is correct.
-the story is not terrible, but it's not great either. Most of it already happened so it doesn't connect to you, the player, directly and you can't interact with it in any way other than watching little movies. The story in the present is, aside from the Zora and Gerudo one maybe, very lackluster and boring. There are no plot twists and the whole story is presented to you from the old man after you beat the Great Plateu.
- lacking enemy variety is true as well.
- the dungeons and shrines feel indeed, very similar to each other. Be it Divine Beasts or Shrines, sadly.
I think these are all valid critic points against BOTW and I seriously hope BOTW2 will fix all of them. BOTW is a great game, but it has many flaws that can be dramatically improved upon.
