YMMV / Adventure Time: Beginning of the End

• Ensemble Dark Horse: Finn's human wife appears in only one page, but she gained a small popularity not only for being cute and gentle, but also for being the closest thing to a closure for Finn's love life.
• Fridge Horror: Imagine what would happen if Finn got erased from existence by Rex alongside everything he did. Just try imagining the Lich running around again, but with no Finn this time and Billy still being a retired, hopeless hero while Jake still being a criminal, Ice King still kidnapping princesses and Flame Princess spenting the rest of her life inside a lamp. And that's just one example.
