Set in the 24th century after a massive war called The Fall, “Alita” takes place in a "Blade Runner"-like shanty city located directly underneath a seemingly lifeless floating metropolis that hovers above on a great disc.
Alita: Battle Angel is an unholy mashup of Blade Runner, Rollerball , Robocop, and The Terminator… all of which, it must be noted, predate the 1990 Japanese manga by Yukito Kishiro this is based upon.
Randomly filching from Blade Runner, Metropolis, The Matrix, TRON, Rollerball and a teenage boy’s wet dreams, it’s more of a scavenger hunt than a movie.
So, if you're looking for comic-book-quality characters, mindless mayhem and postapocalyptic visuals you looked at already in Blade Runner, Dark City, The Fifth Element, The Matrix, Jupiter Ascending, Ready Player One and Mortal Engines, I really can't recommend Alita: Battle Angel highly enough.
In the hands of Rodriguez and writer/producer James Cameron, it aims for the sci-fi heights with its blend of Astroboy, Rollerball, Blade Runner, and Cameron's own Dark Angel.
In other words, Alita is basically Whip It crossed with Blade Runner—and it rules.
