Like everyone else, I'll just jump in and state that this is like a small version of a Black Mirror story, since this seems to be the touchstone for any sci-fi plot that looks at the impact of technology. The plot here is about AR gaming, which most city/town centers will already show you we have, as school kids and older wander round looking at their phones hunting Pokémon. In this instance the technology is contact lenses that allow the pets you design to exist directly in your perceived vision, not just via your phone's camera.
The film does a good job to keep us in the moment, so we are not rushing ahead thinking about where it is going. We get to see things of interest in the main character; the infomercial style starts well, and leads into more of a reality of isolation that connects well with the modern experience (lying on the sofa alone, swiping around on the screen) but extends it so it is highlighted as an absurdity and a little tragic. This is extended well, and the conclusion to the film has more impact because of how well the film has kept us close to our current reality. The visual effects are also very good – technically impressive, but better for being a supporting role in the film and not the whole show.
