'Edge of Tomorrow' is like a live-action video game

Edge of Tomorrow mimics video game respawning.

Video game adaptations have generally been pretty awful. Edge of Tomorrow isn't based on a video game (it's actually based on a Japanese novel), but it manages to feel more like a video game than any game-based movie that I've ever seen, while still providing an interesting and fun narrative built upon a unique time-travel premise.

The movie takes place in a present-day earth that has been invaded by hostile aliens, slowly but steadily consuming the cities of Europe, Asia, and the Middle East, and the combined forces of earth's nations can't slow them down. William Cage (Tom Cruise) is ordered into active combat in a surprise assault against the aliens, despite being a propaganda officer rather than an actual soldier. During the assault, the human soldiers are ambushed and slaughtered, but Cage manages to kill an alien only to be boiled alive by the alien's acidic blood. However, Cage gains the alien's ability to go back in time to reset the day after he dies. So when Cage dies, he immediately wakes up back at the army base just prior to the invasion to start the day over again.

Cage gets stuck in a "Groundhog Day" cycle, constantly reliving the same failed invasion over and over again. He tries to change the outcome, but plays such an insignificant role in the grand scheme of things that his efforts are all in vain, and he must repeatedly experience the invasion until he has effectively memorized every event. In each repeat cycle, he gets a little bit better at staying alive, just like a video gamer playing a trial-and-error level in an old-school video game (think Castlevania, Contra, Ninja Gaiden, or the more recent Demon's Souls). He learns the location of every alien, every mortar shell, every landmine, every piece of flying debris, until he can essentially walk through the invasion with his eyes closed either avoiding or eliminating threats with virtually no effort.

As a gamer, it was very interesting for me to watch a film narrative that is completely based around one of gaming's central conceits: respawning after a character dies...
