Willow asks Buffy about what she saw, and the vision is shown to the viewer: Inside the Hellmouth, the First has an army made up of thousands of Turok-Han vampires.
Laurel Hostak of the website Screen Rant says, "When Chloe dies by suicide following the First's intrusion, Buffy uses it to scare and motivate the remaining Potentials.
Buffy's transformation into a ruthless general is in stark opposition to her character; even if she's hoping to toughen the Potentials up, she has lost the empathy that always made her strong.
So we have a rather unfortunate scene where Buffy, a very white woman, confronts a group of African men, insults their cultural practices, and acts as if she knows better than they do.
The source of that heinous rite of passage that the Watchers Council makes a Slayer go through has nothing to do with stuffy white men sitting around the table.
"[7] Vox, ranking it at #126 of all 144 episodes on their "Worst to Best" list, writes, "It's an interesting wrinkle to the Slayer mythology that will pay off beautifully in 'Chosen,' but a) this episode suffers from the dread season seven sameness, and b) it’s kind of weird that the origin story for the Slayer power that the show treats as empowering and beautiful comes with so much rape imagery, no?
It also marks the beginning of the painful mutiny of the Scooby Gang that culminates in 'Empty Places,' although here it seems almost justified, as Buffy, one by one, insults almost everyone.
All the goodwill and energy gained at the end of 'Bring on the Night' is seemingly torn away by Buffy’s lecture, while the vision she received from the Shadow Men strips her of much of the confidence that she'd been building.
Club writes, "The real, fascinating question that 'Get It Done' raises is: What is the line between destroying a person and lighting a fire under them?
"[9] Entertainment Weekly calls it "one of the season's worst episodes," faulting the writers who "are busy putting another nail in the coffin of the show by demystifying the Slayer mythology... [T]hey’re offering her the power that she needs to defeat The First, and she rejects it — not on the grounds that the offer is a trick, but because the sacrifice is too much to ask.
... After the many times we've been subjected to variations on her 'It's all about Power' speech, this sudden reversal of priorities seems like poorly thought out back-pedaling.
