I personally take great enjoyment from the utter ridiculousness of the books, so I don't understand all the serious criticism. I have read J. R. Ward's Black Dagger Brotherhood vampire series, and there is some fucked up shit in those books. Trust me, that woman is disturbed. But those books are insanely popular in the romance genre. What makes that nastiness okay but Twilight's wholesome silliness so destestible? For me, the cheesier the better. (As evidenced by my turning to my friend in the theater after seeing a trailer for "Fired Up" and saying "I am so going to see that.")
And I'm annoyed by all the criticism because all these people are looking down on us Twilight fans, as if we're lame losers or something. I suggest they all lighten up. If Twilight wasn't your thing, that's fine. But some of us like a story about cute teenage vampires that romp around the rainforests of the Olympic Peninsula. And you know what? That's okay. (Also, these people who don't understand the "phenomena" need to remember that the fan base is primarily pre-teen and teenage girls---and those of adults with a Peter Pan complex.)
I also maintain that this is not at all like my criticism of Carrie Underwood fans. My biggest beef with her is her undeserved awards. Twilight detracters can start squawking in earnest if Twilight starts winning literature awards, but I don't think that's likely to occur anytime soon.
