No pun intended - the 70s called and they want their genre back ... well they called on a landline and no one picked up so ... I reckon that is why we get this and other movies. All kidding aside, if you like movies that have the disaster theme ... well you could do worse than this one right here.
It does look really good, CGI works fine, the tone and the pacing is quite good too. I didn't check if this is based on a true story, but even if not, it is likely to have been inspired by a lot of things that actually happened ... of course you do not wish anyone to find him or herself in a situtaion like this ... if this is your cup of tea, you will like it .. if not, you probably should not watch it in the first place.
