look, i think the film holds out the opportunity for self-reflection, about the audience's own relationship with violence, that you might appreciate. but, just because the film has, i think in the most felicitious reading, a different message than what you would want (a film about the power of film vs a film about how the audience is wretched) doesn't mean that the film "ain't deep." it's just has different aim than what you want from it.

there's room of course for films that rub an audience's face in their own wretchedness, about their own complicity. Haneke's Cache, Haneke's Funny Games, The Sopranos come to mind. they're great, also thematically rich, but obviously to different ends.
