In 2072, when the mob wants to get rid of someone, the target is sent 30 years into the past, where a hired gun awaits. Someone like Joe, who one day learns the mob wants to 'close the loop' by transporting back Joe's future self.It started off interestingly with plot that keeps you wonder why you would wanna kill your future self, why can't you time travel the inception style to fix things, and several other questions in mind to be clear off.
It anyway begin with the story siding on the younger Joe staring Joseph Gordon-Levitt, introducing his assignment routine and his lifestyle as a looper. Pace started to build up when the plot introduces "Closing the loop" where details shall be explained in the movie.
To me, the pace slowed down and turned into hundred minutes of story telling and draggy scene when future Joe (Bruce Willis) was sent to present Joe to be assassinated.
There were of course, future Joe having to escape and work below radar while present Joe being tracked by the mob, but most of the scene weren't about fire gun and ass kicking scene but more toward the new character build up and future Joe's lifestyle and so on.
Once you, the audience find out what's really happening, I bet you would think this is just yet another typical time travel movie or at least I did. It is just another way of executing the almost familiar plot we've probably seen with different cast and technology. I wouldn't say that it is a bad movie, but I think the word draggy fits perfectly and it wasn't that 'mastermind' either.
