The Congress
I really loved this. It puts a nice dystopian twist on the reflexive film and I rate it with movies like The Player and Adaptation (although it's not
quite as brilliant as Adaptation) for that reason. I can't really go into detail without ruining it, but what I can say is that the first act is a little rocky, then it leads into some really fascinating visual and conceptual ideas.
Go into it blind, oh and the soundtrack is amazing.
