It was fun! Yes, interesting take on time travel. I'm wondering if it would actually hold up under scientific rigor, but that's just me. For the purposes of the story it's a neat idea.
Okay, now this is interesting. A friend of mine shares his Plex account with me. I also have Amazon Prime. I A/B'd between them just as an experiment. For some reason the audio with my buddy's version was better than streaming direct from Prime. I only did it for the beginning tho and didn't compare dialogue during action scenes, but didn't notice any issues hearing it when I watched last night.
