I'm very surprised at the lack of attention this film has had on imdb (this is the first review), I can only assume it didn't get the distribution that it deserved. This is an intimate feeling film with a lot going for it. The mystery keeps you interested and it's easy to become emotionally attached to the characters. The casting was solid all of these actors are believable and did a fantastic job with their performances. It seems to have been storyboarded and/or edited well because the structure and pacing of the film seems about right, it's run time is in the sweet spot for what they wanted to do.
If you watch this movie you'll probably still have questions at the end of it but that's fine, I have a couple of different theories as to what the backstory is but I'll leave them out here so that I don't give any spoilers.
Don't be expecting any car chases or explosions, if you aren't you'll love this.
