I watched this movie. Big mistake. If I wasn't being paid I would have walked out.
The whole story is about a guy who meets who he thinks is an ordinary girl. A girl who turns out to be a superhero name G-Girl. But she becomes too attached and the guy played by Luke Wilson starts getting freaked out. The story keeps going.
If you want to know what happens just watch the preview for it.
Pretty much what im trying to say is avoid this movie.
