This is a bit of an odd film to rate as the overall film is very much greater than the sum of its parts. The main issue is the mother, she doesn't come across very well as if the actress was just going through the motions. Of course she may have been going for a more understated performance, but if that was the case it didn't work too well. The father is also problematic, but he's not in the film much so is less of an issue.
The other issue is that the story (to begin with at any rate) is pedestrian and for half of the film you're left with the impression of an average horror movie. Thankfully that changes as the film nears the end and it all starts coming together. In fact by the end of the film it feels like a superb work, genius almost.
So on balance it's a good watch, but worth persevering with to experience the conclusion which is worth the time in it's own right.
In this concept-led chiller a single mother moves into a new house with her young daugther - soon after the young girl loses her first tooth and begins to recount that she is having nocturnal visits by a tooth fairy. There is no "happy ever after" here - FAIRYTALE is the dark and twisted story about a demonic Del Toro-like Tooth Fairy hell-bent on revenge.
Fairytale is available from Amazon (and is a decent watch)
