Looper is an interesting action movie that will make you think, but it is very likely that it will discombobulate you.
In the year 2044, organized crime groups use time travel illegally to eliminate their enemies and hires assassins known as Loopers. Joe (a heavily made-up Joseph Gordon Levitt) is a young Looper who encounters a future version of himself from 30 years (Bruce Willis) and faces the dilemma of carrying out his mission and knowing why his future self has a mission of his own.
The good thing about this film is that you can take it at face value and enjoy the basic time travel premise of the story-- something like Back to The Future or The Butterfly Effect. But once you dig deeper and try to understand the totality of the story, you'll end up thinking in loops. I also like how the film clearly defines the motivations of each major character, as well as the dilemmas it presents pertaining to time travel.
Looper is a genre-breaking film that has too many dramatic and sci-fi elements to be boxed into an action film. For sure, it's smart, but it may be too smart for its own good.
