Like 'Monsters', another failed attempt to cross-genre, this movie is really more about the protagonist getting back to his wife. The alien invasion is more like the obstacle. That is about the most positive statement that can be made about this movie. As mentioned, the use of flashbacks were incoherent and not well paced, meaning you spent more time trying to figure whether it was present or past than learning the backstory. Primary issue is acting. Knowing that there are hundreds, maybe thousands of unemployed actors that can act, why do directors settle on a main character that makes Kirsten Stewart look good? There is an alien invasion going on, and people have the same level of emotions as those waiting in a grocery line. Main character has one confused look for most of the movie, regardless of the scene. I lost 90 minutes of my life, I'm warning you not to do the same. Sharknado 4 is an upgrade.
