About the story...
I couldn't help but react to our friend radiobirdma's review of this film.
I agree that the script was a little confusing because it was out of focus: the story really is about the social rehabilitation of a monster (Pellegrini), seen through the different phases of the process. While I haven't read Carlotto's novel, I was told that's what the story really is about, and I could feel it in the film, but also felt -- like many others, I'm sure -- that the result was kinda like a mish-mash of a few shorter films, or, better put, a TV drama in a couple of 30-minutes episodes. That, I believe, is why the film lacks homogeneity. Once you get over the "episodic" format -- hey, life sometimes seems or feels like that! -- you can start to enjoy a little more the big picture.
Anyway, that's my two-cents.
