Okay, I’m going to need a moment here. The whole “immortality serum” subplot? What in the name of poorly thought-out plot devices is that nonsense? They test it on random slaves like it's some kind of mystical lottery. It’s an experiment, yet Diana’s like, “Eh, let’s just throw in some brimstone, some argentum, and hope it works.” She even says, “None of you are strong enough to be a threat to me.” Really? Are we supposed to believe that this sad excuse for a villain could hold her own against even a moderately intelligent adversary? She can’t even properly mix potions! Her “science” is so half-baked, the only thing “undying” here is her incompetence.
The Climax: Because Why Not?

Now we get to the climax of this nightmare—Julia takes the potion, and it's just... wow. She doesn't die, but she doesn't get much else either. She gets shot, absorbs a soul, and wears the dead dog's cloak as some weird, unnecessary twist. What? What is this? This is the epitome of lazy storytelling—you want a character to be cool? Give them some unnecessary “power-up” and hope the audience forgets that the plot's a disaster. This is like a low-budget B-movie where the hero is suddenly indestructible, just because the plot demands it. I’m almost waiting for Julia to start speaking in cryptic prophecy next.
The Final Nails in the Coffin:

The police force arrives at the end, and the captain just kills the villain with no effort whatsoever. Diana is dead in an instant, like she’s just an NPC you kill for a side quest. The police don’t care about the slaves. It's almost like the author didn’t know how to wrap this up, so they threw in a random police raid and pretended it was meaningful. Oh, and the best part? The slaves are thrown into a mass grave, like it’s the ultimate commentary on how unfair life is. Except it’s just a cheap attempt at making me feel bad without any real emotional weight behind it.
