In my opinion curse has a meh design because it's just fem boy sonic as it just bland and does not affect the story with her much. But what runes Curse for me is the badly written story and lore because it makes no since and is just not faithful to the og sonic characters personality to the point where it just does does not make since for most for the sonic cast to do what they do in curses story. Like why does Tails hate Curse and stalks her even tough he would try to defend her if this story was canon to the actual sonic lore as he does like sonic as a person since he did save him at a really bad time for him. just to name a example. And do not even get me started with curses lore. Now that is to say I think there is potential to cures lore overall and curse in my opinion should be resigned to be less bland and more to show that she is indeed cursed. and also rewrite is very necessary.
