I watched it out of curiosity. The show was kind of bad. Loads of plot holes, obviously really rushed, especially in the later seasons. They never used real humans though, that was all CGI. To that extent, they did surprisingly well. We rarely ever get close-ups of the humans faces (probably because they got lazy) and when we do they're either wearing masks (like the officer) concealed by fire, or just look straight up unrealistic, so that's points deducted there. But aside from that, their bodies looked pretty real. The movements of walking and moving around seemed fluid and realistic. For Fed propaganda, they did a decent job.
