To me, the Twilight series took the whole thing to a bit of a... stupid level. Vampires get a random super power, they sparkle in sunlight (seriously, what the fuck is that?!) and they seem to be unkillable -even by sunlight- unless they're killed by one of the flamboyant illuminati vampires by getting their head ripped off... or whatever.
There's many interpetations of vampires, sure, but one wonders what made Meyer call these "vampires" rather than just come up with something else or just treat them as the more traditional vampire. (They sparkle in sunlight, seriously... What... The... Fuck?!) Don't get me started on the whole "is Jacob a werewolf or isn't he" thing. (He's not.)
Then there's the whole thing where this book/movie series is sold and presented as some great teenage love story when a deep interpretation of it shows that it has pretty misogynistic attitudes and bad messages for teenage girls.
(Remember girls, if a guy you really like breaks-up with you he doesn't really mean it. So mope around for several months, cry out at night like a crazy person and if you threaten to kill yourself it'll make him come running back to you! Oh, and doing dangerous things will give you that same "rush" you feel when you're with him. And you should manipulate other men to get what you want.... and C-Sections really suck.)
And, honestly, as much as I've seen this movies and heard about the stories I'm not sure where any Mormon/LDS symbolism comes into play. My best friend who is LDS doesn't see any symbolism in it either. Whatever, Meyer. Oh, and Bella has such a terrible character flaw in that she's so perfect... except she's not because she's clumbsy.
God these movies suck.
