For all those who didn't understand the premise or hated the ending, spoilers

Rating: 9/10 (25 March 2020)

The movie is about a man stuck in a situation that he doesn't understand at first, assuming that he needs to be debriefed, since the last the last thing he remembers was being on a mission. He soon discovers that he is inhabiting the body of someone else, later to find out that he is doing it over and over for the span of 8 minutes. His mission: find out who bombed the train.
This is the weird part. The bomb already went off, so how can he revisit and explore the world where something has already happened? I gave this a 9 instead of 10 because of how poorly the writers explained this, so I understand why some people couldn't swallow what I think they the authors were trying to convey in the rewrite.
At the end, the movie would have been just great, perhaps a classic, if the main character's last moment was frozen in time, a snap shot of everyone in some sort of bliss. Instead, our main character is alive. Not only is he alive, but is able to leave a residue in what is assumed to be the true base reality. The only hint the writers gave us is that our main character says, "Tell Dr. so and so, that he unleashed something bigger than he realized" or something to that effect. The story should have made slightly more clear that we all have within us all the information of the local universe, so for that 8 minute heat impression left by the hand on a surface analogy, that universe can be explored in so far as it could be in real life. People that didn't like the movie, but still liked the Matrix, kept their mind too closed.
