Shahrukh khan tries to put in everything in the movie. There's a limit to what can be digested. From a small town to a star-struck glamorous life and yet then to NASA in the US is too much for a short-dwarfy man, who isn't literate, educated,prudent and socially accepted otherwise.
Unnecessarily long and stretched as well.
Was expecting better from the movie .
There's a saying , "Too many cooks spoil the broth"
Similarly in this movie, "Too many versions of one man spoil the show."
