3/5 starsTron returns with a third instalment in a series that began in 1982 with a film that showcased then pioneering visual effects as a computer programmer was pulled into his own software.The belated 2010 sequel, Tron: Legacy, was something of a disappointment, despite featuring one of the great movie soundtracks of the 21st century by Daft Punk.Tron: Ares flips the original on its head. Instead of a programmer finding his way into “the grid” – the “digital frontier” inside his software – the program comes into the real world.In this case, Ares – the “master control” code – takes the physical form of actor Jared Leto for our convenience and understanding. Designed by unhinged tech CEO Julian Dillinger (Evan Peters), this sophisticated AI soldier is the next step in cybersecurity.The problem is, Ares only lasts 29 minutes before disintegrating. Dillinger needs to find “the permanence code”, something his rival game designer Eve Kim (Greta Lee, Past Lives) is also seeking.
