Are the Star Wars prequels a better love story than Twilight?

Again, Padme was a teenager doing an adult's job while Anakin was a prepubescent that she did her best to mother while she was with him.

Yes, it is absolutely creepy for that to turn romantic.

Yeah it's definitely weird that kids that met each other as kids have kids later in life.

When it comes to questions of romance between them, teenagers and kids are not the same thing. Padme met Anakin at a time when she would have been considering romance (at least generally, if not specifically with him), while he would not have been. He then spent the next 10 years being forbidden from developing romantic attachments to anyone else, after which he reconnected with the pretty girl that was so nice to him when he was a kid and so few other people cared, so of course he developed a crush on her. She, on the other hand, had 5-6 years of normal(ish) adulthood and the emotional maturity that comes with that, and her last interaction with him had amounted to "he seems like a nice kid."

A 24-year-old dating a 19-year-old is already a bit questionable (at least in our world), given the substantial difference in life experience between a fresh adult and somebody who's been adulting for several years and the gap in emotional maturity that often entails. Toss in how impaired Anakin's emotional maturity was and the fact that Padme knew this, and it's more than a little creepy.
