I feel this is basically an insult to Indian audience by trying to act like it's a science movie, based on real incident, woman empowerment and what not just to release it on Indian Independence day to emotionally provoke people to watch it and not to be critical towards your own knowledge. practicality, wisdom.
It's in a way insult to both ISRO, their mission and film making over all. Because you are basically emotionally manipulating people to get tangled to drama, situation of being driven by nationalism mood, using the real story, and release on a day where no one should question you action. Recipe for success shouldn't be defined by manipulating people emotionally.
For an analogy, it's basically enemy is singing national anthem infront of emotionally driven army who are hiding during the time of war and then enemy is shooting those who raise up their heads to respect the song. So anyone who are standing up in the situation emotionally driven will surely going to get a head shot not to think practically and logically is the whole case of this movie. This I would call as Charlie Chaplin syndrome. (Check youtube "Charlie Chaplin - Shoulder Arms (1918) - Shooting scene" you will get it)
Though I gave 2 points because, drama is good at some points and few people's acting is good like Vidya Balan. She is the only person to look up for in acting and rest are just to cherry in the cake. It's very sad though because such a good real story could have been made such epic proportion but is made such hastily just to mint money it feels. And jokes/humor is so bad. It's basically feels childish immature film made just to mint money or manipulate people in the disguise of entertainment.
Very much fact to say,check on wiki, this script seemed is taken by "SpaceMOM's" film. Mission Mangal seem taken that script and hurriedly made it just to mint money as soon as they got the producers for it. Check out Radha Bharadwaj's SpaceMOMs you will see the same movie angle but still to be released. It's very disappointing if Mission Mangal copied the script and because of money power corned the original
