One star because Ranbir's acting was the only thing great about the movie.
Poor direction, storyline, plot, and cohesion in the storytelling.
I couldn't think of one good thing about this movie apart from the fact that I laughed once.
Women are disrespected throughout the movie. A lot of the content in the movie is setting a poor example for the coming generation.
Most importantly, the movie was based on father-son love, and there wasn't any story about that. Also, no emotions in the movie.
I can keep writing about how horribly disgusting the movie was. Probably a lot of 1-star reviews talk about a lot of things.
All 5-star reviews look stupid and meaningless, I guess all the fans trying to praise Ranbir that's all.
The directors didn't only just make a poor movie, I made a poor decision buying a ticket for such a movie and wasted 3.5 good hours of my life.
