The Twilight Saga. I admit I was obsessed with the 책 when I first read them. Then the 영화 came out and that obsession with the 책 kind of just went away. The 영화 were just awful. Maybe if they had a different cast, the 영화 then would have been better. Who knows.
That Percy Jackson movie that came out in 2010 and The Hunger Games. I'd read all the THG 책 before seeing the movie and I expected it to be as epic as the first book was. It wasn't. I really like the series and hope the 2nd film will be better.
