Crevasses open up in the earth just behind the fleeing protagonists. For hours.

Rating: 1/10 (30 March 2010)

Yep, that's the movie. Science very much like that in "The Day After Tomorrow", which was very, very, very, very terrible. Really terrible. Continents move "23 degrees" in a matter of hours without causing any apparent negative consequences for the inhabitants. Fortunately, no character development is necessary, because there's no time for it between the fleeing and the crumbling. Then when the end of the story finally comes, they can't figure out how to end it for another 20 minutes.
I wish I understood why IMDb thinks a review does not count unless it has ten lines. Because you shouldn't even have to read this paragraph. Please don't; just read the first one.
