I usually don't write these reviews but in for this film, I had to.
Usually, reading professional reviews gives you get a sense of the movie and, in an era with so much content, if it's worth spending the time to watch it. But for this film, in my opinion, they are completely off.
This is not another bland sci-fi movie.
It's a beautifully shot film (with great aesthetic references) and a well developed storyline that made me stay focused and intrigued right until the end. It's a movie that walks on a fine line of possibly spiraling out into deep sci-fi and isolating itself into a one character driven long plot. Somehow it manages to fulfill both without being either.
I recommend watching it like you're in a theater: lights out, cellphone off and no interruptions.Enjoy.
