Factual error: The villain drops the elevator full of waiters and catering staff; the display gives him no indication of whoever is in each elevator, but we can maybe assume it was a staff-only elevator and he knew it (it surely had no markings to indicate it). When Kate reaches the ground floor, everyone inside that elevator is lying unconscious in the corridor. I could understand if the survivors crawled there, but everyone is simply KO meters away from the elevator as if the impact happened there and not in the elevator shaft with a devastating buildup that had to be vertical and contained for obvious reasons.

Factual error: The villain triggers the detonation that causes the elevator with Kate's dad and stepmom to start falling. After an initial hiccup, the cabin begins a freefall. Only after this real fall begins and the elevator already fell a few floors down, Batwoman lands on another elevator. Pauses. Shoots her rope to the top of the shaft. Hooks it. Pauses. Shoots from Chekhov's gun the double edged harpoon, which effortlessly sticks to the top of the elevator cabin and halts the ruinous fall with a smooth slowdown and no oscillation. All of that happening because somehow the elevator in all those seconds is just a handful of floors lower, even if it was plummeting at breakneck speed from the very first shot. (00:35:40)
