Plot questions (spoilers)
Great film, it deserves a much higher rating here. The only flaw (besides minor plot holes) is that it wears its influences on its sleeve a bit too overtly.
I had to watch it twice to understand the whole plot in all its details. Nevertheless some questions remain:
1) The giant face machine ("The Thing") remains unclear. How does it relate to the cloning and life extension? Does it serve as raw material for the transplant of body parts, or is compiled of the left overs? In one scene the mayor even talks to it as if it has intelligence.
2) Tite-Fille's memories of being (operated on?) in the factory were never explained, or did I miss that?
Flavien's mother must have been really retarded not to make the obvious connection that he was her son, considering he looked just like Junior, Clovis and Faustin.
