No, I think it's the "romance" in the book that has girls going ga-ga. But I have to admit the character's beauty contributes a lot

There's wasn't really much description on how they look. Edwward, at least. We're told all about his eyes and hair, the color of his skin, and something about his jaw line, but that's about it.

We're told he's very attractive. I always figured that was intended so that we could picture our own figure of ultimate beauty, since everyone's ideals are different.

How many times does she have to say how perfect Edward looks? We get it already. And since alot (not all) of fans are like "Oh Edward light your sparkler in me" or "Rawrrr you bad doggy Jacob" then I'd say yes, yes I do think the main attraction are the characters physical features.

However, most of the fans rarely admit it.

the most comments I see from twilight fans in this club are how hot some of the characters are I never see any comments about why they like the plot or anything :/

I totally agree with Mongoose09

In most comments I see in this club from Twilight fans, nobody ever talks about how the characters look. People say they see them talking about the looks all the time, but they probably can't find many.

I don't think it's the main attraction.
