Zelda games straight up have a very mediocre story. And often nothing about their world building makes much sense either. They're definitely a series built only for fun gameplay. Everything else is just glue to hold the gameplay together.

Personally, I love the gameplay and exploration, but you're definitely right about the story and voice acting.

PS: dodging should be the same as jump (x). Lock on with ZL and point the movement stick to the side you wanna dodge to, the jump. If you pull the stick back, you'll do a backflip. Whether you want to jump back or to the side depends on the enemy attack (eg, do they swing horizonal or vertical?). If you dodge juuuust before the enemy attacks, you'll get a slow motion during which you're prompted to spam y to rapidly attack. Especially useful for tough foes like lynels.
