I just saw another great Argentine movie. It's called "Plan B". I loved it because it was marketed as this really wacky romcom but it's so quiet meditative, and very natural. The chemistry between the 2 leads was awesome. It's avail thru Wolfe Releasing. Highly recommend it!
I agree about A Home At the End of the World and Soldier's Girl...love both of them!
I've got a lot of favorites,but the ones that are really standing out right now are gay/transgender films like Breakfast On Pluto and Bad Education. I also love XXY, which is a film from Argentina about an intersexual teen. It's really amazing.
