The original Tron was very experimental. It had an out there concept (which I can really respect for sci-fi), it had a pioneering synth soundtrack, and pioneering visuals. It was kind of novel but a lot of people found it boring and convoluted. It found a cult fandom of nerds like this guy and to the rest of the world it became a punchline for a weird flop of a film. Even the Simpsons took a shot at it.

Decades later they made a sequel that nobody seems to hate. Tron Legacy was actually well made, it's got decent cinematography to it, they built sets, the CGI looks great with the possible exception of a de-aged face that does not hold up, and Daft Punk's soundtrack is universally acclaimed. Most moviegoers agree that the plot of Tron Legacy exists. It was a success; it made more than its budget, it sold some tie-in merch. The weebs I knew around that time had pictures of either Olivia Wilde or a light cycle as their desktop wallpaper for a few months, and then the world moved on. It wasn't bad, but it's still a niche fanbase compared to The Matrix or Pirates of the Caribbean or Star Wars.

And now they've made another for some reason. It's got very little to do with any of the original characters, Tron isn't even in it. It's about virtual characters emerging into the real world, released at a time when people are worried about AI and the effects it's going to have, and it stars an actor basically nobody likes. I've heard mixed reviews about the NIN soundtrack.
