Who said it was shitty? I do believe it is the best Zelda game, but that doesn't mean it's without faults.
It has faults, such as the super easy northwest dungeon, anything involving Yunobo, or that atrocity of a final boss.
The combat as a whole is definitely not a weak part of the game, if anything it's one of the best and easily the best combat Zelda's had. Battles require actual brains to be won, as you are usually overpowered by enemies and have to be on your toes and use everything you have, including the environment, to your favor. The fact that the Trial of the Sword is not only focusing on combat, but again approaching it in this interesting way of building environments around it, and giving you few tools to work with, is just awesome.
As for the story being the worst in Zelda history, no. Just because 98% of your play time with the game doesn't revolve around plot points or cutscenes doesn't mean the 2% that do are underwhelming - in fact, those 2% alone are not only among the best stories in any Zelda game, but also among the longest and most complex, with several interesting characters rather than just 2 or 3. If anything, I'd say the only Zelda game that has a definitely better story is Skyward Sword, all the others are on par at best.
