I liked it. It felt like three movies smushed together. I don’t think it entirely worked — in particular, the emotional core of the movie is the estrangement between the father and his daughter, and it disappears for massive chunks of the movie. But for a show that runs nearly three hours, it never really dragged, and although I checked the time a few times, I wasn’t impatient for it to end.
Plus it actually takes relativity seriously. Props for that. And the first part of the movie, set on an Earth sliding into ruin, did a great job of suggesting a complicated history without hitting you over the head (unlike the ending…).
Just one more comment: binary doesn’t work that way.
