The movie started with something really interesting; It started to become amazing in the middle but it was normal in the end. The concept was great but they could have made the movie much much better. I was really impressed with the concept of the movie but in the end, it was same "super heroes all the way" movie.
If it was an animated and a bit funny movie(Like big Hero 6), it could have been much better. I believe its only one time movie which is also coz of the concept.
