I saw this movie on a Valentine's Day and have been in love ever since.
Sure sure, Pan's Labyrinth may not necessarily fall into a horror movie category still, the movie revolves around so many horrific things. From monsters in human and non-human form, to bloody revolution, to death, to childhood fantasy creatures that if seen in real-life would be downright horrific.
This jaw-dropping film is a must see, even one for the whole family (if you're children are into fantasy stories). There is a reason this film won 3 Academy Awards.
Watch this film. Love this film. It will love you back.
