Excellent film by Almodovar.
Very rich, lots of layers - sounds like I'm describing a cake! The men (and the main characters are both men) are quite quite or maybe unexpressive. Along with the simple language they employ (or seem to employ - it's not like I can speak Spanish), this means that their thoughts can only be read through their actions and expressions.
Wish I could say more about it - but I'm in a hurry, so just see it!
See it again? Definately.
