It's like the Russian version of a typical Hollywood disaster movie. ("Daylight" is very similar to this one.) So the characters are clichéd, the escape at the end is quite unrealistic, there are no conflict between the characters, everybody just wants to survive. The acting is almost amateur.
On the contrary, the directing, the cinematography and the visual effects are amazing, they're even better than in many Hollywood movies. The main catastrophe and the immediate consequences are shown in a quite impressive way, almost better than in any other disaster movie before.
Because of this, I can recommend this one for watching, but don't expect anything better than a clichéd story.
