Tron changed cinema, predicted the future of tech
Anthropomorphize computer programs and invent a BS way of injecting a real human into a computer and Tron is what you get.  It's complete nonsense!  However, if you can suspend disbelief, Tron is a seminal film that has echoed through all of cinema for decades and is a helluva lot of fun to boot.  It is the 80's in a single film.  It oozes style and is a groundbreaking technical tour de force that must not be missed by any serious fan of movies.The sequel is an epic Daft Punk music video that far surpasses "Interstella 5555" and, for that reason alone, is required viewing unless you absolutely hate Daft Punk.  There's a cartoon series, Tron: Uprising, that is excellent even though it was cancelled after one season.  (It stars Elijah Wood, in case you needed another reason to check it out...)Tron may not be the most commercially successful movie franchise of all time, but each instalment of it has been a truly novel treat.  It's may be style without much substance, but what style!  I eagerly await my next dose!
