Reminiscent of Groundhog Day

Rating: 8/10 (25 November 2014)

This movie was one of the best sci-fi-action movies I've seen all year. Story is based on a Japanese novel, "All You Need is Kill", Hiroshi Sakurazaka's debut novel. Reminiscent of "Groundhog Day" because Cage (Tom Cruise) perpetually relives the same battle vs. the aliens, the Mimics, throughout the film. As redundant and potentially boring as this may seem, the film is very well done and exciting.
Cage soon learns that the reason he keeps reliving the same battle vs. the Mimics is because he killed a type of mimic, an "alpha", that has the ability to manipulate time when it is killed, and was saturated in its blood when this occurred. This gave Cage the same power as the alpha, the ability to reset the day, re-live the battle, so that they have a better chance of living the next time around.
The only problem with this, that was not addressed in the film - Why does Cage only have the power to reset the day after he kills the alpha and is saturated in its blood. Aren't there other alphas still out there that still have this ability? Maybe the book explains this better.
Regardless, this movie was great and I recommend watching it.
