Review of The Tomorrow War (2021) by Pyramid79 — 05 Jul 2021

I'm somewhat surprised that from all the reviews I've read, no one has mentioned the obvious time paradox that exist because of the ending. If anything was used from the future, whether that be tangible or information, to defeat the aliens in the past than the obvious conclusion has to be that the time line starts over again and the same process takes place exactly as it did before.

If the aliens are defeated in the past, using anything from the future than the war never happens, the future people never come back to warn them, the serum is never developed and no one would remember anything that happened.

By the speculated science of time travel, the only proper ending given the rest of the story would be, as soon as the aliens were defeated, using anything from the future to do so, the movie would start over with the story being exactly the same.

The only way to defeat the aliens, again given the rest of the story is to develop weapons and defenses to combat the aliens and not deploy them until after the future folks come back to issue there warning.

Or, they could develope the serum, but it wouldn't be able to be deployed until right after Chris Pratt jumps back to the past. This is the only way for the aliens to be defeated, using anything from the future, without resetting the entire timeline.

Pratt's character even mentions this at the end of the film when he says, " She will never know about a future that never existed," therefore neither can that particular present.
