It has the same drive as the Oceans's movies but with a minimalistic overtone. The limitations of the iPhone's sensor, which kills any depth of field and leads to some overexposure in many scenes gives the movie some sort of humility.
It let's the eye settle on the actors, let's me focus on the delivery of the script, puts the people in the foreground. It felt really close to the protagonist, and while I do not claim to understand a whole lot about the details of the plot, I got the gist really fast.
You get a got story, simply done in tight 90 minutes. I really love this!
