Spoiler Alert- Looper Sequel Storyline and Looper story reasoning

Rating: 10/10 (14 April 2014)

I think this movie is brilliant. It has more depth I think than people are giving it credit for. Yes it has a lot of unexplained plot holes but I think this is setup for future sequels. The story isn't just about Joe the looper.
(Spoiler Alert) It's really bridging off to Rainmaker who will grow up and kill the looper's because of the danger he experienced with Joe's future self hunting him down.
But also since Sara slept with Joe I think she's pregnant and will conceive another child which will be Rainmaker's brother and it will end with Joe junior's (Joe's unborn kid) killing Rainmaker (Cid). Just because his mother was spared doesn't change the fact the character was potentially dangerous and was influenced to be evil cause he lost his mother doesn't mean he will change and doesn't guarantee Sara will still not be killed since she was suppose to die.
So Cid will grow up becoming so strong beyond his control but with Joe's Kid also with the same gifts be the only one to stop him. Kind of like a Kain and Abel story but with a different ending twist.
So what's with the looper's having to do with Rainmaker you ask? Well what if the organization sees rainmaker as a threat and sends someone back to try and kill rainmaker? That would make them a threat and a reason to kill them all and stop time travel. But his one weakness is he won't be able to kill his brother who was born from a looper which closes the rainmaker story and gives life back to the looper storyline giving it open ended for other stories to be made for it.
This is just my input on what I would do for the story. Doesn't mean this is what has or will happen. But I think written correctly it will justify making a suspenseful and tragic storyline to continue it's edgy style. Maybe even not giving Joe's Kid powers can work as well. The connection is he figures out who his father was and finds out Young Joe's decision didn't work out as expected and needs to be resolved by stopping rainmaker.
