This movie was terrible. Don't waste 19.99 on it. There are plot holes large enough to fly a plane through and the acting is simply horrible. Butler slips in and out of his accent constantly and Scott Glenn's talents are wasted here.
Among other plot problems, they don't even explain why they have to go to Greenland! Why is there no disaster shelter in the US? I don't want to give away the plot but is you watch this, you'll have similar questions.
I had low expectations for this movie and I was still disappointed. Sharknado is more realistic and better acted
