I think itts because how the story goes and itts different for alot of other things.. Itts got a little for every one itts got romance, thril, fighting, suduction and alot more.. And the fact that the movie has vry attractive people and you just can't not look att them.. Like Emmet for example..lol..
i really dont know. I think its because its a thriller and a romance without being trashy. Its (mostly) clean and it beautiful. Its a tragic and happy love story. Kinda like Romeo and Juliet. I think what makes it addicting is the story. Sure you know whats gonna happen but each time you read it or watch it you discover something new.
Everyone is addicted to Twilight because it is easy to relate to Bella and they feel that they could meet vampires and have the experiences she has in the books. Its so great because its a story of struggling love between the more gorgeous person ever and an ordinary girl and the books are really passionate and action packed. Its not like most romance books. It has many more and different difficulties between the lovers. Stephenie Meyer gives very good descriptions and makes it feel like your really in the book. Twilight is just awesome
