These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Really, back in the day Yoko was a case of She Cleans Up Nicely, due to her hippie image making her (and John) look shaggy and homely, when as you can see above her features themselves were not ugly by any means. Same applies to John, once a young Bishounen mostly known for looking like a dirty hippie.
Never Live It Down: No matter what she did with her career or for John Lennon's memory, she'll always be remembered for the Beatles breaking up while she happened to be married to John. Charity work that she takes part in are frequently bashed online solely for the fact that she is Yoko.
Ron the Death Eater: There's plenty of fair criticism to be made of her, but her Hatedom's image of her as some evil golddigging sorceress who used her Eastern magic to seduce John Lennon and break up the Beatles definitely falls under this category.
She Really Can Sing: Opinions vary in which songs did her voice actually sound good (or at least "listenable"). Her more conventional songs are often well-liked even though there are some that do prefer her avant-garde songs with her screaming vocals more.
A good early example of this could be from the B-side of the "Give Peace a Chance" single, "Remember love".
