do i agree whether or not this film is the greatest of all time?
this film depicts the reality of life being even though the hero is wronged he still does not get his bike back by the end of the film (This is life) at the time this film as made yes this could be the best film of all time.
the bike to me represented life in a form due the fact that he needed in order to do his job and create the money to survive in his time and place in the world.
The use of the non-professional actors was actually a very good idea due to the fact life doesn't have a save point or re-spawn time or do over if you make a deathly mistake you stay dead if you are looking for realism than Neo-realism is your type of film. life is not scripted and there is no second take and this film depicts that quiet well for a film.
the fathers character arc was interesting to watch develop as he goes from a poor man in Italy trying to figure out life and keep trucking on then his bike is stolen and eventually he tries to steal a bike so he can do his thing and live on happily but at this point he was apprehended (where were these people when his bike was stolen?)
The son loves and looks up to the father i feel father was the world to the boy and he wanted to grow up to be like him. Maybe less after he tries to steal the bike.
