I assume Extinction is the result of two people having very different ideas for science-fiction thrillers, with one idea being about a guy who sees's visions of an impending disaster and the other concerning a family trying to survive an alien attack. So taken away with both of these ideas, the two people decided to merge them into one movie without figuring out first if the two separate ideas would actually work together properly as a singular property. Turns out, mushing these two concepts into one movie, along with shoving in a nonsensical climax overstuffed with big twists, results in a total dud of a movie, one that just gets worse the longer it drags on.
