If they would have played just the trailer repeatedly for the entire duration of the movie that would have been 100x better than the movie itself. What stands out in this whole film is Ranbir's acting and every thing else is mediocrity at its peak. It's a long four hour movie and if you already got the ticket, the best thing you can do is go there and sleep in the royal seat and if you can't fall asleep there just put your headphones, don't expose your eyes and brain in the film, it's for the betterment of your mental health, and if you want to do something productive their than just look at the chairs, the roof, the floor, the stairs and try to figure out the physics,maths, bio, history, geography everything behind it, it will be a lot better
