We are living through a really depressing time in cinema, and this movie is a perfect case study. It is built on a really strong premise... About 30 years in the future, an alien species attacks earth and decimate most of the human population. The dire situation leads the army of the future to use an experimental time travel procedure to conscript people from the present to fight in a last ditch effort to save humanity.
It's an interesting concept that a competent writer and director could do a ton with.
But this movie isn't written or directed by competent people. Instead, it's directed by a guy whose only major credit was the Lego Batman Movie and written by a guy who has done effectively nothing of note... And unfortunately, they pack this movie with exposition, explicitly telling us important, emotional beats instead of showing any of them on screen. It has zero sense of when or how to reveal crucial pieces of story information, it introduces characters and events for no reason, and presents people who are objectively making incredibly dumb decisions as very smart.
There's just so much wrong with this from a filmmaking and storytelling standpoint, and it just makes me sad for the industry as a whole.
This should be better. There's no excuse.
