Not to be confused with the 2010 horror film 'My Soul to Take'. 'My Soul to Keep' is an interesting concept. Everything that happens here might merely be a kid's interpretation of what's going on, and not reality. Kids often make up stories and events they perceive as real - whether it be due to an over-active imagination or to cope with something they fear.
I enjoyed the characters and the setting in the big house. The acting was pretty good. I especially found Brandon Matthew Layne good as Dad. Maria Wasikowski, however, seemed too young to have a 16-year old daughter and didn't sell the Mother-character to me.
The film effectively utilizes children's fears to create an interesting, somewhat creepy movie, with some good visual effects. There's actually not much happening throughout the movie, apart from what the children believe to be happening, but it nevertheless remains engaging - with some highly effective, scary moments. Loved the score, too. The film proves you don't need blood, guts and gore to make a great horror film. And what an unpredictable, good ending...
