Unexpected Ending, so so Story

Rating: 6/10 (3 January 2013)

I have high expectation with Looper. When I read about the review, wow, looks fab one! About time travel, assassin. One I should have not missed. Looper told us about the 'future assassin' called looper, who killed people from the past. The bad guy sent to the future, where the looper exist. The head's villain covered, when they arrived, the looper instantly shoot them on the chest. As the payment, the silver bar could be found inside the villain's clothes. If the looper get golden bars, means they killed their selves because the contract had cut. Joe (Joseph Gordon-Levitt) was one of the top achievers looper. He always on time, kill the villain, take the silver bar and switched the bar with money. At night he's having fun and tipsy.
One day he was shocked with a loud knock in his door. Seth (Paul Dano) beg him to hid him from the others looper. He did the worst sin that a looper can do, let the villain escape. Seth was realize he's going to kill her future self. He told Seth in the future there is the big villain called the 'Rainmaker'. He was going to kill all loopers. Joe hid Seth but at last revealed it because his boss threatened him would take his silver bar saving. One day Joe felt something wrong, because the villain that should killed by Joe, didn't come on time. After some time, the villain come, hit Joe with his body, till Joe fall, and his cover head overt. That withstand Joe pull the trigger, the villain's eyes! Why it just look familiar and resembles like mine? Wondered him. Knowing Joe stand still, that old guy attacked Joe once again till he faint. Joe awake and find his way to meet his old one, his future one, Old Joe(OJ) (Bruce Willis). OJ asked Joe's help, as he wanted to eliminated the rainmaker, which is in Joe era still a kid. OJ was so hurt because they kill his lovely wife. Joe rejected and said, he should kill him now, and do the right thing. Eventually he agreed to help OJ. OJ only had series of number, he had no idea what is that, but that was the only one direction about Rainmaker. OJ find out the location of the rainmaker. He ordered Joe to go one location, while he will go to the others two locations.
Joe arrived in old farm. During his journey he's got shoot. He met Sara (Emily Blunt), a single mother with one kid. She's is a strong woman, and always brought a gun everywhere. As they talked, accidentally Sara saw Joe's paper which was written that serial number. Sara shocked and asked how he found out about that? who are you? Evidently that was her son's social number and birth date, Cid (Pierce Gagnon). Was he 'Rainmaker'?
The ending was unexpected. I was like, what?? But the whole story is OK. I can't say good, but it's OK. :D
