About this series I can say, I have read all of the books, and I watched 3 of the movies and was semi-subjected to the fourth. I read the books simply because my sister bought them, and I had nothing else to read. Once I started it was like a trainwreck, and I couldn't look away despite how awful it was. Bella was the most annoying character in the story, which sucks since she's the lead. Imo, most of the werewolves and several of the vampires were more interesting than any of the main characters, but they're nothing spectacular either. I really dislike this series, as it seems most people here do. I will even agree with what someone said pages back about preferring to watch Dora the Explorer.
What I will say in favor of the books is that Stephanie Meyer gives us other writers inspiration. If that can get published, I know my book can.

This series is disgraceful to the word "vampire," and if I want to read about vampires, I will read Dracula, or Carmilla, or some other series that actually makes vampires out as what they are, as opposed to sparkly sissies.
However, I will admit to having bought some merch- nothing much just a $2 bracelet set, and that was because I liked the way they looked, not because they were Twilight. They were New Moon wolf stuff and I really like wolves... and it was just $2. If it had cost any more than that I wouldn't have bought it anyway.
...Also I have a fleece blanket my aunt for some reason thought I'd want that has Edward on it.

It's too soft to get rid of it, so I pretend it's Cedric rather than Edward, but I don't even know where it is anymore.
