THIS is Art
I very much liked your Movie, it´s good to see that there are still people out there, who do not only try to make you laugh or smile, but also serve equivalents to the entertaining industry.
Other than most of the other reviewers I personally think that the ending even reinforces this feeling of injustice in the viewer, I don´t know how you felt watching this movie, but with me it started a fleshcutting feeling of known scenes. If the other pricks in the movie started whining when the scapegoat or whatever you want to call their victim, fell down, it would easer the viewer, for you would get your desired happy ending.
This piece of Art followed on of Dürrenmatts attributes for a good drama, it ends with really the worst possible ending thinkable: No one cares and as a matter of group pressure, even the "girl" who first wasn´t sure if to push the button engages in a sexual stimulating act of lust, "to commemorate"...
It kind of reflects the behaviour of most people nowadays, horny for media sensations.
