I just watched the movie, and it touched me how they handled the message to make the world a bit better.

I have some issues on work, where bad things happen and frequently I see ppl claim "it's bad because it is", as we have to accept it, but these ppl keep doing actions that cause and increase bad things. I see they keep perpetuating it, while they could move their effort into avoiding it and changing it.

Here we have the bomber who briefly says the world is bad and he expects it to get better after shocking ppl, while what he's making is just cause suffering. The ppl on the train are usually sad worried with their daily issues and being rough to each other. Colter, instead of just accepting their and his fate and do what he's told to, keeps trying to save them, and on the last session challenges the comedian into making everybody laugh. On the original dimension they were making each other's life a bit worse then they die, and on the new dimension they're laughing together.

It's kinda surreal and romanticized, like him creating a perfect world, but it was nice to watch. And made me smile :p
