Look through the reviews. Those from 2006-2018 are in the 3-5 range. Those from 2021 (like this one) see it differently. We've all seen the cheesy post-apocolypse or post nuclear war movies or killer bee movies. What they all have in common is that there is no reality to compare them to--so they could be accurate predictions or just pure bunk.
I'm sure those who saw this in 2006+ thought "Pure bunk. That would never happen!" I just watched it in spite of its 4.7 IMDB rating, as I was curious. Wow! OK, the movie is pure made-for-TV B-movie fare, but what were the writers thinking? Worst case scenario? Or did they have gifted insight? The almost unbelievable accuracy of the predictions is enough reason to watch this.
