A movie with good concept .but , it is assumed that both the world's are same everything except , the laser gun and the children's. Which u can't assume as same . Even a small change , can change things.atleast u could have shown in different houses. One world has one parameter and another world has different parameter . It is realistic , but the real problem is an apple can be send to other world is logical. Even u can send parameters of that world to them. But how they can send it to us, with the same parameters of Thier world.
