This isn't a perfect film, it's not high-budget, it's an end-of-the-world disaster flick. Anyone going in expecting anything more is severely delusional. There are some flaws, a few corny lines, and the ending is slightly lame (but not totally). There have been FAR worse disaster films. It is definitely not a 1-star film as some would have people believe.
The directing and acting in this was above par. The story line was very cliche, very predictable, nothing unusual. It does however have some decent special effects. I particularly liked the acting of Aleks Paunovic, the Russian electric lineman. In truth most of the actors do a fairly decent job. The film starts out interesting and maintains its momentum through both episodes. I suspect it is better to binge-watch it online rather than lose that momentum in a 2-night micro-series.
Several reviews here are extraordinarily harsh. One has to wonder what they were expecting going in. You don't go see a Transformers movie and complain that it's about giant robots, nor go to a hamburger joint and complain they don't have gourmet food. This is obviously a low-budget, made-for-TV disaster flick, and people are knocking it for being a low budget disaster flick? Get real.
This is considerably better than most films of this type. I found it interesting all the way through. No, it's not hard science (does anyone here even KNOW hard science when it comes to dark matter?). There's a lot of supposition, conjecture and imagination going on. It's not intended to be cerebral fiction.
Overall an entertaining film, which is all one should expect it to be. Not the best film ever made, but by no means one of the worst as some "reviewers" here would have us believe. If you have three hours to kill, it's worth a view. People giving this movie an unbalanced 1-star review are doing no one any favors. If you don't like B class movies, don't watch B class movies. Duh.
