Fantastic watch, will watch again, and highly recommend.
This is one of the most unique and interesting sci-fi action movies I've ever seen. Doing the entire movie from first person perspective is an amazing feat all on its own. If you watch carefully, then the cuts are really subtle if they even exist in places where you would expect them to be. There are a few points of lost consciousness, but those are the more obvious ones.
Because it is a "First Person" movie, Andrei Dementiev literally carries the movie through the camera, but Sharlto Copley ("District 9") is the repeating character that helps drive most of the movie, so he would be the traditional carrier, as opposed to the mute camera. Danila Kozlovsky and Haley Bennett give great supporting roles as well.
The problem with the main character being "super powered" is that they need drawbacks to balance their benefits so they can "power creep" to match / exceed the villain by the end of the movie, and this follows that formula really nicely and in unexpected manners, unless you've seen "Crank 2: High Voltage".
It definitely makes it immersive and enjoyable, and there is even a very well written plot happening.
