Now, see, I "read" Twilight #1 and 1/2 of #2 via audiobooks. I couldn't force myself to listen any more, so didn't finish #2. I figured if I had read it with my eyes, I might have skimmed the more boring sections and perhaps finished it. But by this time, I no longer cared about Bella or Edward, and only slightly cared about Jacob, so I was done.
As a teacher, I think anything that gets kids to read is great, and have not discouraged my adult friends who LOVED the series from reading it. I also loved HP--read it to myself, read out loud to my kids and we all loved the magic of Hogwarts.

My husband would even come in and join us in the evenings when we read those aloud and my kids would give up video games to listen to the next chapter in the story.
