I really like The Vat of Acid Episode, and I get why it's so loved. But for me personally, it felt very clunkily written and dragged out. The pacing felt very odd and the whole episode didn't really fit together for me, and each scene was just stretched and stretched out to fill the runtime, because in reality not much really happens. I like the concept, I just feel as though the way the whole episode fits together isn't the most well done. But I understand why other people love it, for me it's just good.
