I liked it... Why do you think it was a total waste? I like the twist at the end, once you realize it, you then think back throughout the movie and go "Oh, yeah I can see it now", but don't know it until they give the twist away.
It was corny. The Special effects were so so and the acting was lame. But a fun movie to see on the big screen.
Yeah, I saw it due to my friend's urge of wanting to see it just because he heard it was cool. I guess the movie is not of my type but it is still good to watch just because it talks about that book.
