Meaning of the movie
1. Incredibly stupid FPS video game.
2. Class warfare in Spain:
a) Bea = lower class petty criminal. Apparently bad, but basically decent, and screwed in the end.
b) Quim = middle class creep. Apparently weak, but triumphs over Be and the shooters, who are
c) Youth = Spain's future. Oh, and their dad, or gramps, is the Fascist past come back to haunt the middle class.
So basically the movie is a Leftist criticism of Spanish politics. Not quite incredibly stupid, but close.
