Ever the sci fi optimist, I read the 5 star reviews and felt hopeful that the lesser reviews were somehow wrong. That proved to be a rather large miscalculation on my part.
This is a very, very unsatisfying movie - long on dramatic gazes and heavy, sorrowful music, but very short on substance.
The contrived, overblown, and preposterous dramatic sequence that occurs during the journey from one arctic base to another betrays a complete lack of understanding of both cold water immersion and arctic survival. It's almost bad enough to be comical.
The most intriguing questions raised during the film are left completely unanswered in a rather casual but infuriating way, and the ending is the kind of deflated fizzle that you'd expect from writers who have no talent or imagination.
All in all, a big disappointment. Two stars is the best I can muster, and that's being generous.
