The reason why people may like Bella is because she is a blank character, girls who read twilight saga books can put themselves into bellas position instead imagining themselves as someone else. But Bella...shes just a normal.
thats probably made NO sense what so ever :L anyways
they may like her because in most books its all happy characters etc but with Bella shes sort of depressed and that can bring people to be interested in her because they may experience a sad moment in life and think "oh wow im not the only one, even if shes made up" but like i said before she comes across as being normal. we can relate to her.
I Don't Like Bella very much, But I think her, Edward and Jacob all have flaws that make me what to chuck the books across the room. MOSTLY during Breaking Dawn. I hate the fact that Bella gets everything she wants and doesn't have to give up anything. I Love the Twilight Series, but Breaking Dawn was rough. But that book was the main reason I don't really like Bella.
