Any conversation dealing with time travel it can easily become an endless debate about the technicalities, ethics, paradoxes and impossibilities of practicing time travel. Time travel is messy and because of this it is a bit of a cheat when used as a literary device. It can get the writers into very tricky situations when the impossibilities begin to pile up, or it can be used to completely wipe a slate and start anew. Few writers have ever gotten it right, but when they do it is usually beautiful. Rian Johnson’s Looper gets it right within its own world. Unlike most time travel stories, Looper embraces the paradoxes. But more surprisingly it wipes them away in a rather clever - and intense - conclusion.
