I absolutely love spoilers. Without some, I just get bored. I love to know what is going to happen, because it makes me want to get there already. For example, I got bored with Lost because I felt like the writers had no idea where they were going. Now that it's over and I can read every spoilers possible, I want to watch the show, because I know it all lead to somewhere rather than just have the feeling that there is a lot of suspens to keep the audience interested.
It's also because of the spoilers I had about Illyria that I decided to watch Angel. Otherwise, I wasn't really interested.
And I've stopped watching Pretty Little Liars because as long as I don't read spoilers that make me want to catch up, I just feel like the writers don't really know where they are going, and I feel like a suspens slave.
So yeah, I love spoilers. A lot.
