Overview: Set several centuries in the future, the abandoned Alita is found in the scrapyard of Iron City by Ido, a compassionate cyber-doctor who takes the unconscious cyborg Alita to his clinic.

When Alita awakens, she has no memory of who she is, nor does she have any recognition of the world she finds herself in.

As Alita learns to navigate her new life and the treacherous streets of Iron City, Ido tries to shield her from her mysterious past.

Verdict: Co-written and produced by James Cameron (who was too busy working on Avatar sequels to make it himself) and directed by Sin City and Spy Kids’ Robert Rodriguez, this sci-fi movie is based on a cyberpunk Manga series about a female cyborg in a dystopian future.

Alita is said robot, found in pieces on an Iron City junk heap by scientist Ido (Waltz), who puts her back together again. Her body may be spare parts but she has a human brain and begins to remember her past as a warrior.

She also finds time for romance with Hugo (Keean Johnson) and he introduces her to Motorball, a fast-paced, gladiator-style violent sport in which the ultimate winner is promised a new life in the wealthy sky city of Zalem that hovers above the slums below.

Of course, there are bad guys, including killer cyborg assassins and the scheming Vector (Ali), but the movie is dominated by the special effects.

Alita (Salazar), with her oversized eyes and robot body is one of the best effects of all, but while you will marvel at her creation, Salazar never gets the chance to deliver enough warmth for you to care about what happens to her.

In fact, despite being visually impressive, the whole movie feels cold and uninvolving, while the plot seems borrowed from numerous other movies and stories, including – to name just a few – Rollerball, The Hunger Games and Ghost In The Shell.
