Your description sounds pretty much like what I was expecting from seeing the trailer: big dumb popcorn film with lots of special effects. At least the special effects are good according to your report, unlike some other disaster films (cough 2012 cough).

I honestly let out an involuntary chuckle at the cinema when during the trailer, the voice over said something like "oh, no, our climate control system has malfunctioned" and then showed the scene of the people frozen in the desert, it just looked so absurd I could not help laughing... and regarding cringy cheap dialogue, one can also get a taste already from the trailer (car cashing scene "Marry her" Ugh!).

Well, at least you didn't have to pay! ;-)
