Your point falls flat when you see Kim. Different shows but Kim is also like something you described but she's not boring.
I agree there's a unnecessary hate boner for Skylar in bb fanbase but her character is not that interesting. Even Walter is a pussy 99% of the show but for some reason he's portrayed as some tuff sigma male xD. Unrelated, we are still here talking about these characters after more than a decade. Vince Gilligan is truly talented.
