Sean Kelly’s review published on Letterboxd :
As essentially surrogate director for James Cameron, Robert Rodriguez doesn't really get to add too many personal touches to Alita: Battle Angel, save for a few cameos by regular collaborators Jeff Fahey and Michelle Rodriguez. However, the film does show that Rodriguez is able to handle large scale blockbusters, with Alita having the largest budget ever for the filmmaker. Alita: Battle Angel also allow Rodriguez to bounce back a bit, after the lukewarm response to his Machete and Sin City sequels, which resulted in a five year hiatus from filmmaking, with the exception of the From Dusk til Dawn TV series.
While you can’t ignore the problems Alita: Battle Angel has in regards to white-washing a Japanese manga and falling into various gender stereotypes, as a piece of popcorn entertainment, the film is quite enjoyable.
