This is an excellent film. Script is original, performances are above par and it's a very hilarious, very enjoyable, very entertaining comedy.
The first half is mostly comedy, whereas second half of the movie is slightly emotional and very romantic but nevertheless enjoyable.
The story is very original. Vicky Arora is a careless young man who is unemployed. Doctor Chaddha who runs a clinic for infertility finds in Vicky a super sperm donor and tries hard to convince him to become a regular donor for his clinic. This makes for a great story. The performances are superb. Annu Kapoor is extremely comical. Ayushmaan Khurana who debuted with this film in both acting and singing is a versatile performer. Dialogues are so funny that you're bound to burst in laughter.
It's an excellent film in many senses. First is-it's a movie on a 'taboo' subject and yet it's so convincing and funny. It goes on to prove that whenever hard work is put with originality you can produce a superb film which would be well liked by audience as well.
Music is also amazing. I think this is one of the best Bollywood movies ever and definitely one of the best comedies of all times. I enjoyed watching this movie and it made me burst in laughter in the first half and made me shed some cold tears in the second. A great entertainer indeed. I would give it 8.5 out of 10.
