Yeah. I think it's more art style than big eyes in general. Some styles can pull them off fairly well while others just... can't.
Well... that conversation is going to end as soon as it starts tbh. I'm not watching any anime right now.
I don't see what the eyes in specific have to do with it. But if we have to talk about big eyes I can't say that I utterly dislike them because one of my favorite mangas have characters with pretty big eyes due to the style.
I liked the character designs but they were definitely not the best I've seen. Out of all the characters there was one, maybe two characters in which I really liked their designs. Alas, it's not the main male or female.
I like them when they add an extra genre which isn't drama or comedy to the factor. Even then I can be relatively picky? I think before Hyouka it was CLANNAD that I finished, but I had never finished After Story so.
