But the Anakin/Padmé relationship itself isn’t earned. There’s no reason why Padmé should fall in love with Anakin (and several very good ones why she shouldn’t).
Especially after how creepy Anakin is. I guess George expected us to be okay with a relationship without virtually any chemistry just because both parties are attractive.
Han and Leia may not have the best chemistry I’ve seen/read in Star Wars but at least they make sense together.
