I genuinely think these are terrible (sorry to anyone who loves them!) Soggy, passive, Bella just seems to hang around limply, not questioning anything, not taking control of her own circumstances.
As has been said, Bella is terrible to be held up as a heroine. She's so passive and weak - it frightens me legions of young girls around the world have latched onto her "love" story and hold it up as a desirable thing.
It's not the genre and need for a suspension of disbelief. Much, much more fiesty, funny, and fierce are the Sookie Stackhouse novels (True Blood). She's sassy, doesn't take any crap from anyone, isn't afraid of nor gets swept away by the romance of the vampires.
I'm sick and tired of women being so passive in this genre. Waiting around to be taken away or bitten or changed or whatever. At least in the SS novels and TV series, the heroine fights back, is indignant at the arrogance of the vampire characters, refuses to be possessed or changed by them - she has a strong moral compass that is centric to her world view and is true to her actions. She actually has a personality as well, which is more than Bella ever had!
I would much prefer my (future) daughter to hold up the SS novels as her heroine than Bella :)
