Only at the end of this movie did I find the illogicalities of the plot annoying. It was as thought the writer and director started out with a very good idea, but could not resist embellishing it with complexities regarding the dreams, premonitions and mysterious symbols.
The result is that A leads to B, and B leads to C - but then we learn that somehow C and B lead to A, and so on. What could have been a coherent, logical plot-line becomes a mess.
Having said that, I must admit that the movie is watchable to the end, and the actors are engaging and convincing within the constrictions of the storyline. Beatriz seems a little too naive and vulnerable for the revelations of her true intentions, and whoever gave her that appalling haircut should definitely not give up his/her day-job. The repeated references to "2001" seem unnecessary and distracting, and I feel that the same plot material could have been conveyed better in some other way.
Overall, the film could benefit by some judicious cutting, especially the pointless overhead sequence in the toilet, which has nothing to do with anything. Perhaps the director shot it as a student exercise, and couldn't resist shoving it into a movie somewhere?
However, despite its numerous faults, I recommend this movie as enjoyable and entertaining for the most part. Just put your logic on hold, and enjoy the acting and photography.
