Sisters are neutral at best due to both characters being inconsistent (and in Kitty's case, slightly overrated) as well as being treated more like plot devices rather than individual characters for most of their run.

They need to break up because the relationships have proven to be bad for the characters involved (except Shawn who's already a bad character even without the relationship) and again making said characters feel more like plot devices rather than individual characters.

I'm someone who hates the "It's just a cartoon" argument so please don't try to use that as an excuse. Also, yeah Island was unrealistic at times but nowhere to the same extremes as Pahkitew Island having an artificial island full of robotic animals.
