I found Looper to be kind of underwhelming. I liked the actors in it, but the story was all over the place. Why don't they interrogate the victims to pumped them for future info and get rich? In the future where time travel is illegal the mob is more worried about being found with dead bodies than with a time machine. Any decent prosecutor and investigator will put two and two together and have them convicted of murder with the time machine as the murder weapon.
I also thought that entire telekinetic plotline to be unnecessary and it took away from the premise of the film. They could've shown more of how evil that kid will grow up to become.
