I really think that zero is a fictional love story which deals with human emotions. All the characters did a great job. The movie could have got crispier by not stretching it. Although it's a movie where a life lesson is there that how a human can get greedy and ruin his present to achieve more. It is a very different love story and has been able to maintain an equilibrium. First half is funny and second half is emotional. Overall I would recommend everyone to watch this film because it is a good love story and great chemistry between Anushka and SRK. I would give 3.5/5 to this movie .
