Usually circus shows offer great entertainment and amusement to us. Hundreds of acrobats, clowns, magicians, animals like lions, tigers, elephants and many more are well showcased in circus shows. Every skit of a circus show astonishes the spectators. Eventually, a great circus show leaves audiences a memorable experience.
Even though, circus shows are meant to offer ultimate pleasure, audiences can't identify themselves with anyone just because a circus show is a collective effort of a group of people such that there is no chance of specialized heroism.
In contrast, movies are primarily designed to establish the heroism in greater levels as crores of audience identify themselves with heroes of the movies. It doesn't mean to degrade the other cast and crew of any film. If all technicians and the heroes put collaborative efforts, the better results will come out. Finally, one should admit the fact that the story and all other departments of most of the movies should depend on heroism in the substance of the movie. That's why heroes should always be elevated and glorified in movies. If at all a hero is dominated by other characters in the movie, even if the film scores a big hit that may not help to the hero anyway.
