If at all any film gets any deviation from above span of run time, then that film has to acquire an appealing content in it to please the audience irrespective of its run time. It is a common practice most of the films are the target of critics due to lengthy run time.

A common movie lover wants to watch a film with a minimum run time of 130 minutes. Since 2.0's run time appears to be very short, the movie needs to cater the needs of audience in the prescribed duration.
