I think the japanese don't really understand how to pitch a movie.
First I saw Sadako throw a baseball as a stadium, and now this.
We get it: She comes out of a 2D screen. It's 3D. What matters to the viewers is if there is something more to this movie than 3D. The audience (at least outside Japan) was amazed by 3D back in the early 50s, and we kind of expect more by now.
