As a comet scheduled to be seen in the sky as it passes the Earth changes course we follow the Garrity family as they fight for survival. 

Greenland is not the disaster picture that you were expecting when you saw it was headlined by action hero Gerard Butler. This has more in common with Deep Impact than Armageddon with its focus on how society falls apart in the face of impending doom and how human nature can be both a force of good and evil. Whilst there are sporadic thrills this is not a blockbusting special effects extravaganza. 

Butler plays structural engineer John and actually sticks with his Scottish brogue. He is separated from his wife Allison (Morena Baccarin) but they are trying to make it work for their seven-year-old son Nathan played by Roger Dale Floyd who is keeping up the tradition of annoying American child actors with a mop for a haircut. Whilst shopping for a neighbourhood barbecue he gets a presidential notification that he and his family must be at a military airforce base for emergency relocation. This request is initially met with disbelief and then anxiety at the fact they were the only ones chosen at the gathering. 

The journey to be relocated to a bunker in Greenland obviously does not go to plan and the meat of the film is how the family strive forward whilst witnessing the behaviour of those around them. 

I have to say that on the whole I quite enjoyed this film. It absolutely was not what I was expecting and I think that was a good thing. It had moments of emotional turmoil and intensity throughout which kept it interesting even amongst some of the more dubious drama and scientific beats. 

I will be intrigued by the discourse that some of the science in the film might generate because whilst I am no expert there were at least two moments where I was barking at the screen at how ridiculous and impossible the events were.
