I am a 62 year old Amazon Bestselling science fiction writer, and have seen literally thousands of movies in my life, as well as all the great science fiction series. And I rate this film among the best of all time in the scifi genre. Wonderful action sequences, fantastic world building, and a terrific performance for Alita. She is the most human character in the movie. I could believe this was an amnesiac teenager who is seeing the world for the first time, the wonder in her expressions, the soulful looks, the many heartbreaks. Highly recommended. Don't let the critics keep you away from this one, which must be seen on the big screen to be fully appreciated.
