This is a gorgeously told tale from Celtic mythology that follows the adventures of the young "Ben" and his sister "Saoirse". Their mother died whilst giving birth to the girl - who is unable to speak - and they lived in an isolated lighthouse (I'd love that!) with their widowed dad "Conor" until being sent to live in the big city with the grandmother. The colourful narrative now follows the pair as they determine to get back home to their dad. Along the way, we discover that "Saoirse" is no ordinary girl, and that her powers, thanks to "Ben" and his fairytales, might enable both of them to engage in a challenge to free some magical creatures trapped in the realm of the humans. The animation is charming, the characterisations likewise - they are well developed and retain their innocence and childishness throughout. The soundtrack is also a thing to enjoy - a typically Gaelic affair with haunting melodies and jaunty themes that all add richness to this simple but intriguing story. This is a fascinating vein of legend that is really underdeveloped by cinema internationally. Here we have a delightful introduction to those stories and this really is well worth and hour and half of anyone's time.
