And now that I actually am watching Flesh and Blood.
This episode has an insane amount of consistency errors that I didn't even notice the first time around because at the time I hadn't seen a Hirogen episode in three years.
First of all, if you want to re-use aliens, don't give the ship 10,000 ly jumps. And if you do, there's absolutely no excuse for any alien type you've seen, except the Borg, to appear again. (Or, at least write super-engines into your script if you do to justify it).
Second, whoever wrote this episode thinks Hirogen are pretty much Klingons with a very particular vocabulary. When Janeway said "It isn't like the Hirogen to play possum, no way it's a trap", I laughed out loud. Isn't that exactly what they did in Hunters to capture Tuvok and Seven?
But, if you ignore those consistency problems, it's a good episode along the 'AI rights' theme.
