The movie has some ideas. The protagonists' psychologies are quite simple and straightforward. The two actresses do a decent job, and overall the plot is quite decently structured. The character of the girl's mother is not really believable though (they should have taken an older, more angry-looking actress!). The major flaw of the movie, though, is in the editing: the images of some scenes seem to be patched together like a Picasso painting (speaking of Spain!). They would have required some more accurate editing. Much more importantly, I am firmly convinced that in the end, Asia is not dead: at the beginning of the movie we hear her say "Eloise, I dreamed I died". The scene where she is hit by a car is therefore part of the dream (which explains the absurdly cold reaction of Asia's boyfriend when she's hit!). With the final scene of the two girls leaving together, then, we get back to reality. The different light used in the final scene aims at underlining that we are on a different plan than the rest of the movie, which is (entirely? or in part?) a dream. This is my interpretation of the finale, but if it's correct, it is not well communicated at all to the viewer!

p.s.: the movie is not in Spanish, as somebody wrote: it's in Catalan, what a nice language!
