This movie is a curiosity! Full of interesting ideas on a conceptual level and breathtaking visuals. It's an ode to space exploration and exploration theme prevails (especially visible in the introduction sequence). As such, the emphasis is much more on mystery and discovery process than on suspense and action and this is where the critique, I believe, is coming from. Still, the fans of hard sci-fi and space exploration will be satisfied. I was. The story is quite original. The music is also fitting and the editing is very rhythmic (resulting in some gripping sequences). The scientific aspect of the movie is convincing as well. Theonly thing I'd love more of would be more straightforward storytelling.
