I dunno, i was kinda on the fence, but this one kinda pushed me off.
So the whole shtick is to take people from point A, and move them to a future point B (in time).... With their newfound numbers they'll win the war at point B... cool beans, awesome movie, had some epic set-pieces. Point A, however, is still marching diligently towards the situation Point B had found itself in....??? This is why i hate time travel movies. They're always bullshit.
I wouldn't be surprised if there was some plot mcguffin that kills the bad guy in point B's time, and enemies in all other timelines fall dead (oh how convenient would that be lol).
I'll probably still give it a watch, but i'm gunna assume i'll be adding to the list of reasons why time travel in movies are just a middle finger to the audience.
