Strange is the first word that comes to mind after watching MirrorMask but an enjoyable strange.
The film stars Helena, a girl whose parents are circus owners and performers and when her mother falls ill and she blames herself because they had fought earlier. Helena falls asleep and when she wakes up she finds herself in a strange world that is slowly being consumed by shadow. Helena finds out that there are two lands, the City of Light and Land of Shadow, and both have queens and someone looking like Helena stole the "charm" from the Light's queen and so now she can't awake and now the shadows are taking over. Helena finds out that the "charm" is really the MirrorMask and she sets out to find it and restore the balance.
Acting in the movie is okay but really nothing compared to the art.
Visually the art in the most of the movie is a mix of digital graphics and live action in a darker theme that is a very strange but fits the setting.
Music is also strange as most of the music isn't full orchestral but sounds like a small band from the circus.
MirrorMask is a strange fantasy movie with a so what interesting story but with art style that should be seen at least once.
