The story is not unique, but actually a good one. However when you combine that good story with bad acting, poor CG, terrible dialogues and immense plot holes, the output is inevitably below par.
I say bad acting because any mimic, gesture and voice acting are so exaggerated that you feel an urge to slap their faces to help them back to their senses. Other than a few main roles, every character is either shouting hysterically or acting overly self-confident.
Poor CG is acceptable in consideration of the lower budget.
Terrible dialogues are everywhere. Either there are lots of cut scenes or several writers authored the script individually and than shuffled the pages to make a scrambled innovation. The result stinks like a bowl of deteriorated and uncooked scrambled eggs.
Plot holes. Oh my! Countless. Self detonating non-explosive things, inverted hands with absurd axis shifts in camera view, unexplained relationships, and most importantly climate defying "everything"... In a movie of which the plot is about extreme climate change, some clothing freezes in water, which is surprisingly present in extreme low temperatures and some organic tissues survive in the same water source.
All in all, it would have been a masterpiece, toppling "Oblivion" of Cruise in many ways.
If you really have a two-hour spare time and the movie is free, watch till the end, against all odds. The ending is satisfactory. But the journey may get really boring and your thumb would reach out for the stand-by button any time.
