Kicked out Los lunes al sol (Fernando Leon de Aranoa / 2002) after watching it again. Still a very good film, but not as powerful and subtle as the first time. Actually it is a bit formulaic, and has only a few really great scenes (though the screenplay remains strong). Rating was 70 out of 100, so I had to put it off the list. 
But Battle in Heaven entered instead, and 109 movies remain in the game 
After having watched Oh brother where art thou again, I removed it from the possible contenders list.
