To me The Sonata deserves a higher rating than it actually got on here. Andrew Desmond did a good job with this movie. There is a certain dark athmosphere created, mostly by the excellent soundtrack. If you want to make a good horror movie (even thought it's not categorized as such, but it should) you need good sound effects and music, that's just essential and in The Sonata it's just perfect. The acting wasn't bad either. I would have liked a bigger part for Rutger Hauer but the rest of the cast did certainly well. The Sonata isn't a very visual horror movie even though there are some good frightening scenes and jump scares, it's more an athmospheric horror movie that has it from the sound and story. Not bad at all if you like that stuff.
