Shahrukh as a midget has portrayed the character with the same facial expressions and emotions that he portrays. He has acted well. If you watch it then you will notice that in the first half his face is literally copied from the fan movie minus his nasal features and in the second half he is shown with his usual face. The plot keep you somewhat or marginally entertained for the first half. Second half is mind numbing stupid!!
Katrina Kaif has acted amazingly well and it leaves no doubt that she had a bad break up with that ranbir kapoor fellow and he has been given a royal snub in this movie.
Anushka Sharma, seems to shake a lot or almost none portraying her character in this movie. It is like one day she shot the movie and was 110% in the shoes of the character and maybe after a break came back and completely forgot how she was supposed to enact the role.
The plot as mentioned is mind numbing stupid! Spare yourself and watch for free if you really really have to on TV.
Last and not the least, someone the Bollywood folks feel it is their birthright to belittle India and naming the chimpanzee as Indya!!! was not liked by anyone in the audience.
