The most notable fandom that this concerns is Harry Potter, more so when JK Rowing was still writing the series. Basically, there are three different kinds of people within these fandoms: people who hate Twilight and love Harry Potter, people who hate Harry Potter and love Twilight, and those who like both, such as the folks who started the website Twilight Source, who are very much involved in Mugglenet, one of the biggest Harry Potter fansites out there.
Then, of course, there's the movies. I'm not a big fan of them; the actors didn't quite live up to my expectations. There's also a lot of critism against Meyer's modern version of the vampire, like their sparkling in the sunlight.
But, we're here to talk about books. You probably know the story; Bella Swan has just moved from Phoenix to cold, wet Forks, Washington, to live with her dad. She's fitting in OK, but there's someone she just can't figure out: Edward Cullen. This isn't just a story about vampires, it's a story about love, and I find it entertaining and suspenseful, a really good read. There are things I don't like about it (coughJacobcough) but I enjoyed the series.
Happy reading, and don't forget that the next movie, New Moon, starring Kristen Stewart, Robert Pattinson, and Taylor Lautner comes out November this year!
