In the world of Yorgos Lanthimos, adjectives like 'disturbing' or 'unique' are common. But this time, things are seem slightly closer to reality, making it all even more sickening and nauseating. In a good way, of course.
Watching EDGE OF TOMORROW is like you're playing an RTS game with unlimited lives. It's an expanded, war version of GROUNDHOG DAYS, except that some of the formulas do not work that well. The more you get into the movie, the more you find there's something wrong--and you can't stop to re-think what you've just had because this movie keeps you moving (or accelerating) forward. That's why it's exhausting; it wants everything to end fast, with all possible (but ineffective) ways it has. Which is bad, because the premise is nicely introduced and, well, everything's fine in the beginning.
