Pretty much what I said in the title. The scientist's sentiments is a bit more heart-warming(*), but aside from that, if you like this episode, you'll find exactly the same sort of stuff in mini-series-with-in-a-series "Mindy and Buttons" which appears within Animaniacs. Well, except...
Only other difference, is being a spin-off from The Boys, this show had to add in lots of carnage for no particular reason other than they probably think it'll be popular with their audience. I'm not sure - maybe some people really think just more carnage is funny for it's own sake - personally, I can take it or leave it and lots of blood and guts doesn't virtually nothing for me in entertainment, neither good nor bad, which is why I think this episode isn't all that different than any episode of "Mindy and Buttons."
Ironically, because an adult human body holds about over a gallon of blood, the amount of blood spilled in this episode is actually unintuitively less than there should have been given that amount of carnage.
* - I'm being obscure about the "bit more heart-warming" not because it's complex by any stretch of the imagination, but rather, only so I don't have mark this review as "containing spoilers."
