Removing the familial relationship is so much better because the having them pull a sister out of a hat yet having it be an established character only for it to go absolutely nowhere not only shrinks the universe but is just generally the single worst piece of writing in the entire Saga and I’m including Rise of Skywalker in that statement. It’s incredibly clumsy and embarrassing and I hate it.
It doesn’t go nowhere, it’s used by Vader to taunt Luke.
Acting like this is worse then The Rise of Skywalker is so insane it makes me think that you like shipped Luke and Leia in the first two or something, because it takes some major emotional attachment to actually believe that.
