Holy cow, what a steaming hot mess this movie is. It somehow manages to feel simultaneously confusing, boring, cerebral in a terrible and condescending way, and extraordinarily amateurish.
I'm not really sure I managed to follow the plot. It starts with a manned mission to Mars in the near-future that goes awry for unknown reasons, moves on to what is basically a one-woman show about an earth-based astronaut (think drone program , but in space) working with an advanced AI to investigate what went wrong during that mission, and finishes with scenes that I think are meant to suggest a 2001-ish symbolism concept.
But honestly my understanding is based upon a lot of guesswork. It feels incomplete because if I did understand the basic plot correctly it is just filled to the brim with plot holes and bizarre assumptions. And the last twenty minutes is so dull that I fell asleep.
I would just avoid the movie.
