S7E9-10 Flesh and Blood.
The writers want to do another take on rights and sentience so its hologram time again except they choose a very bad anchor for the story.
The Hirogen should be long gone, Voyager is years of Warp 9 travel beyond their territory. But ok they're still around and have this space station just sitting there in deep space completely by itself 1000s of light years away from most Hirogen ships.
They have somehow spread the holodeck technology given to them years ago to the far reaches of their space, so quickly infact its old news when Voyager 'finally' arrives at this training station. (Hirogen must secretly use transwarp).
They are using holodeck technology for 100% of the exact reason that it was given to them but Janeway moans about it being her fault for sharing technology, her fault that unrepentant pathological killers are being killed by their own creations which is exactly what they themselves want.
Keep in mind Janeway gave them this technology to encourage them to hunt holograms in favour of killing humanoids and other biological creatures for Voyagers own benefit and everyone else in the DQ. Again 100% success with this plan.
Despite achieving all the intended outcomes, with no change to the benefit garnered behind the reasons for giving it in the first place, Janeway takes it upon herself to risk her ship and crew to destroy these holograms even though no one is asking for her help, especially the Hirogen.
She saves the crew of one of their ships who are completely ungrateful, and generally make it extremely clear they would gladly kill her and her crew in the blink of an eye if given the chance.
The holograms while sentient turn out to be pretty devious and viscious, funnily enough, exactly as they were designed. The episode comes to an end with the contradictory message that if you have two groups of bad apples the biological ones should be helped and even depicted as the not so bad guys at the end, even though they are really really bad. Even the doctor himself seeing the same flaws clearer in the holograms than the Hirogen.
TL

R
Complete disregard for the lore of the show - ignoring why it was given in the first place
Nonsensical motivation for Janeway's actions
Weak Chakotay and bridge crew for not making more effort to shut down her insanity
Poor moral message
