It’s definitely worth a watch for the visuals alone. That said, I found it paid off immensely more once I watched the excellent Tron Legacy right after and caught all the lovingly rendered homages and nods to the original. If it helps, the original has music done by the queen of 80’s synth, and then legacy has motherfucking Daft Punk doing everything they do best and even showing that they can do orchestra as well as they do EDM.
