I remember first watching the Twilight movie and seeing Edward sparkle... (lol) I also remember thinking "Hey, they kind of look like tiny flames, not sparkles."
And since old Smeyer hasn't bothered to make an appropriate reason or a reason at all for those damn sparkles, I decided to write down what I think would have been better if she really, really needed sparkles... uuuugh... Of course I don't support sparkles at all, but there is a way the sparkles could have worked and made sense. Bear with me, just... read it.
Well for one, they should not be actual sparkles. Not actual glitter. Dude, where is the sense in that? Nowhere. She doesn't even have a history for sparkles. I think if she really wanted 'sparkles' she shouldn't have made them sparkles, but tiny little flames that slowly, slowly burn away at the Meyerpire body. That's what they look like to me.
Meyerpires shouldn't have bodies that are like diamonds and glitter in the sunlight, because that makes no sense. No. Sense. It would have made more sense if they had normal vampire flesh and bones and the 'sparkles' were just tiny flames that look like sparkles but are not. And also, think about the irony in that. These tiny little flames, slowly burning at the Meyerpire body, yet they look like sparkles, kind of pretty I guess. If they were actually sparkles of diamond or glitter then that's not pretty because it's too overrun by how fucking stupid that is. I think they should have been tiny flames instead of sparkles. And gradually they should start to grow bigger. Come one, that would make a little more sense.
But Smeyer probably didn't do this because that would detract from the character's perfection. I reckon she raped the common vampire weakness to add more perfection to her Meyerpires. You know, instead of having them burn hideously in the sin they sparkle beautifully. Eugh.
I prefer tiny flames that look like sparkles if she really needed sparkles. Tiny flames. Come on Smeyer. Stop cramming your damn character's perfection down out throats. It's not dazzling. At all.
