Cristóbal Richards’s review published on Letterboxd:
Highly recommendable to the time, fast paced, perfect length, and one of those movies that get to delivery fast-food cinema without forgetting they can deliver a message while doing it
Didn't this movie was as half as good as I found it in this rewatch. Even though it was released in 2011, it already did the "dead, live, repeat" plot in a much fresher way than they are usually done.
I really like how the plot twist is revealed at the first half of the movie, so the real plot is tu develop such plot twist.
