This movie is approximately 90% drama, then some Si-Fi, and a little bit of action. The drama is not that interesting, and mostly boring at the time. It later on turns out that it has it's purpose in explaining events that happens later in the movie, but it is still boring at the time. The action is far from good enough or enough of to save the movie, and the Si-Fi part is completely illogical. I see some reviewers describe this as "refreshing" or similarly, but then you will need to accept logic that goes something like this: Things that will never happen, happens, and things that never can have happened have happened... And by the way: Time goes in circles, so things do not happen as they do, but differently...

"Star Trek", "Terminator", "Back to the Future", "The Butterfly Effect", even "Futurama" and so on have handled time travel in a much more "realistic" and intelligent way than this movie. This movie have a completely different approach to time travel than anything that I have seen before, and not in a good way. It tries to hard to be different but stumbles due to the lack of logic and a boring history to create the backdrop for the events in the movie.

If you accept completely illogical stories like for example the one in "The Tomorrow War", you might like this movie, but if you have a logical sense and can not turn it off, you might, and perhaps even probably will mislike it.
