If you are looking for a plausible plot you Have come to the wrong movie.Scientifically the end of the world will be much worse and the downdrafts will end the plane rides much quicker.But It is an above average movie experience and thats what I like about 2012.It is a roller coaster ride and all of the actors did their job.The effects ae super, and it is thrilling.Go see it.leave the children at home.It is not an experience children should have to think about at this point in their lives.
