So we’re just supposed to accept that he’s the son of Han and Leia and just so happens to be one of the strongest Force users in the galaxy?
Yes, because he trained with their friend who’s one of the strongest Force users in the Galaxy? I don’t see how that’s an issue.
Besides, you talk of jumping sharks with everything happening conveniently nearby, but that’s exactly the problem that Leia Skywalker is the epitome of, which is why I hate it. Can we go back a ANH without every other person being a Skywalker? Now it’s just the story of a robot telling his step-brother to save his twin sister from their father. In the context of the film, that has to be the biggest coincidence in the history of coincidences.
