Well, with this being a TV movie in mind, then "Ice" wasn't actually all that bad. But it was no "The Day After Tomorrow" either, although it essentially is the same.
Storywise, then "Ice" did prove to be entertaining enough, although the movie was somewhat suffering from being predictable and stereotypical. But take it for what it is, and the movie is fun and enjoyable in itself.
Effect-wise, well then "Ice" doesn't impress. The CGI were adequate enough, but what made the movie suffer was the horribly fake movie snow that was used in almost all scenes that involved snow, and the equally fake ice walls shown in the crevasse. It was so fake that even a blind person would point a finger and laugh. Seriously, despite being from 2011, the effects were better than such even back then.
As for the people on the cast list, well they did good enough jobs with their given roles. People brought a good amount of enthusiasm and energy to the movie and their characters, which made the movie turn out to be more enjoyable.
A lot of the scenes towards the end of the movie was starting to become too much, especially the amounts of snow that apparently had fallen in record time, and the degrees that they said were outside, yet the main characters were able to withstand that cold in thin clothing, and not a single hint of ice on their bodies. It was like time was running out and they had to wrap up the movie fast and efficiently. And that just made it seemed rushed and not believable in any way.
"Ice" does manage to raise something interesting to think about, such as man's constant quest for fossil fuel, man's disregard for the ecology of the world in which we live, and the heartless nature of the corporate giants. If you are one of those environmental concerned people, then this movie does manage to plant a seed for thought. So "Ice" does entertain and leave you with something once the end credits start to roll.
