“Tron: Ares” (**1/2 out of four) was a flashy but hollow third entry in this influential series about the title program which is highly sophisticated and dangerous and crosses over from the digital world into the real one which results in various C.E.O.’s and A.I. figures (Jared Leto,, Greta Lee, Jodie Turner-Smith, and others) all vying for control and domination. A visual tour de force with lots of psychedelic imagery and visual effects to give hardcore fans and computer geeks their money’s worth but they have to combat a muddled script and story which isn’t always that compelling (and doesn’t always make sense). A definite improvement over last entry “Tron: Legacy” but still feels untouched by human hands and maybe that’s the point. Original “Tron” star Jeff Bridges returns for a few key scenes as Kevin Flynn.
