Writer/Director Nacho Vigalondo does a fine job with the design of this film. This smart time travel feature holds up well in a genre that easily muddles the time space continuum. Keeping the story small but only revealing the needed information has created a taught and exciting film. Is Hector is faced with a horrible decision, or do the time travel limits and rules make his crime forgivable? Is he a selfish man or just completing what has already happened?
Vigalondo is working on a English version of this film slated for 2011. I think it is not necessary since the dubbed version from Spain is quite well done. If you like time travel and thrilling stories this is the movie for you.
