This is easily the worst Rajkumar Hirani movie and probably the worst storyline I have seen in a long time.
The only story this movie has is what they mention in the interview - a village in Punjab where everyone wants to go to London and carry a symbol of plane on their rooftops if a member of their family manages to go.
Beyond the plot, movie had no story. Vicky kaushal is the only one who impresses in a short stint. There was no story, 3 main characters wanted to sneak out using the donkey route, risk their life and seek asylum. What they achieve over there and how their life builds is not covered. They don't even show what profession Tapsee panu does while in London.
SRK stupidly takes her to London and waits for his whole life to come back. Filmmaker also went wrong with the entire messaging. Why couldn't Vicky kausal seem tourist visa to goto London for a day? You don't need English test for it. Why will countries have open borders to get people with no skills, no money and no education.
Give this movie a miss, you will be doing yourself a favour
