My gods, Asta...
I remember several times during the early parts of the anime feeling strong compulsions to drop it, on account of the constant "YOU'RE MY RIVAL!" and "YUNO!" and "I'M GONNA BE THE WIZARD KING!".
It was mostly fine as long as Yuno wasn't actually anywhere near Asta, but as soon as he showed up, my ears bled.
Thankfully, as @Zeroth said, they eventaully toned it down to... Tolerable... levels. xD
Yeah what I heard about the voice actor for Asta was enough to make me consider never seeing the anime, even though I enjoy the manga. Even there Asta's first on screen depiction of not taking no from a girl isn't exactly positive nowadays, but that is him at his worst and meant more as a way to show how big of a determinator he is (at that time to an unhealthy degree) than any lack of respect for her, and was as far as I know only a real issue in the first chapter. He is still obsessed with her at the point of the manga I'm at they just never interacted since
