What,according to you, is the underlying theme of Twilight?

If you're forced to di chuyển in with your father, bạn may just end up with a family of vampires, who are hated bởi your bff werewolves, but it'll work out because one of them will fall in tình yêu with your daughter. ._.

Life choices/free agency.
bạn don't have to accept hoặc take what's handed to you. bạn always have the option to make what bạn want happen.
The Cullens chose to deny their nature and have high morals.
The choice to resist temptation.
Bella chooses Edward, despite the odds being stacked against her.
And so on.

The opposite is demonstrated with the Quilieutes (I always spell that word wrong). I think it adds to the theme, hiển thị what life would be like if bạn didn't have many choices.

That's the main one, I think.
