It is a really cool take on time travel, really mind bending on the first watch. Once you have seen it a few times and understand the way things work, it kind of loses some of the entertainment value.
I think the issue for me is twofold: a) I couldn't connect with the characters-they felt like Asimov plot devices for carrying the story forward and b) too much emphasis on the time traveling paradox riddle. What I mean by the latter was that watching the movie felt more like trying to solve a Rubik's cube but through charts and diagrams. I get that some people enjoy that kind of stuff but I prefer having a solid story line. But I watched it a long time ago, maybe I need to rewatch it with fresh eyes.
The early over the top hacker aesthetic, the ridiculous adversarial hacker battle, the complete misunderstanding of what hacking actually involved (the world has changed). It is all awesome.
Some of the stuff they got right is also cool, the social engineering is still a thing.
Also because of my age when it came out (1995)....I would have seen it in 96/97, I was in my late teens.
