How It Ends is like a movie written by an alien who only learned about human interaction from other movies. Just absolutely a baffling experience. It's well shot with some interesting action scenes, but Netflix's internal house style of movies that completely abandon traditional narrative structure in favor of an series of coincidences and events that provide the thinnest possible setup for the scenes that they thought would look cool is annoying as ****. Learn how to ****ing write.
Also if you're making a disaster movie and not trying to set some smaller human drama in that context, if you're just making a straightforward disaster flick, there's no real reason to make the nature of the disaster a mystery unless the mystery is itself the plot. Like you can make a movie about a mysterious disaster, but the answer to "what kinda disaster is this" needs to be the actual plot of your movie and your characters are gonna need to be scientists or government employees or something trying to answer it.
This was just baffling. The whole movie should've been the third act, or just the first two acts, but together? What the ****.
This makes The Day After Tomorrow and 2012 look like masterpieces.
