I liked Nuremberg pretty well, though I still prefer the 1961 classic Judgement At Nuremberg which was about a separate set of trials, and which featured a young William Shatner.
Speaking of Captain Kirk, that brings me to the sci-fi portion of the conversation. As utee94 noted, movies like Interstellar cover the concept of time dilation pretty well. There was a two-part story in the British sci-fi pillar Doctor Who back in 2017 or so where the entire premise was this massive ship, like 300 miles long, which was in fixed point near a black hole. The ship's engines were perfectly equal to the gravity of the black hole, so it wasn't sucked into it, but it couldn't escape it either. The decks furthest from the black hole watched the decks closest to it on monitors, and the people on the monitors only moved a little bit per week/month/whatever. Time moved so fast nearer the black hole that the crew evolved over thousands of years and a whole separate society developed. Who eventually went to war with the decks further out. The decks with time moving slower had the advantage of better technology and resources in that part of the ship, but their enemies had centuries to develop new technology to fight them. It wasn't super fleshed out of course, because it's Doctor Who, but it was an interesting premise.
There's also a ton of sci-books I read as a kid which dealt with this. Robert Heinlein's Time For The Stars comes to mind, which featured twins, one of whom got sent into space at near light speeds. He returns just a few years older, but his twin was an old man by then. I grew up with so much of that stuff which did address time dilation that it doesn't hurt my brain at all, and in fact I kinda get irked if stories don't take stuff like that into account.
I tend to agree with utee, mostly I just want a good story, but the concept of time dilation makes for an interesting premise, so I like it as a plot device. However accurate it is or isn't......meh.
