Making the movie "Gravity" was hard for everyone involved. A lot of work - I've seen the interviews and behind-the-scenes clips. People kept telling me to go watch it in cinemas, in 3D if possible. Oh, the effects, they said. But there should be more to a movie than just stunning effects. There should be a story and, most of all, there should be logic. Even in sci-fi movies, things have to make sense. And there's tons of things that make absolutely no sense in "Gravity". For instance, who plays ping pong in space?
