i really hate that shit where they intentionally cut the movie in a really shitty annoying confusing way just to make the story ostensibly more cOmPleX rather than just writing something good and relying on its strength like a normal good film

the prestige really pissed me off

Essentially the people have the ability to rewind and fast forward time. To go back or forward in time you need to go through an entrance, red means forward, blue means backwards. Their weapons and bullets have the ability to do this by themselves. The bad group wants to acquire the original source of this power and rewind the entire earth to undo climate change, the good guys believe this would destroy the world instead of saving it. The protagonist is the creator of the group in the future, but sends his associates back in time to recruit his younger self and put an end to this group. The main way they attack in this movie is by one team attacking at one point in time and another team attacking backwards in time. Eventually, the bad guys get all parts of this source and begin the process to reverse all of Earth, but the protagonist wins in the end. This is when its revealed he recruited all these people in the future to save the world, making the ending also the beginning.
