Even though a 10/10 run is hard to accomplish, some anime pull it off on the first try. There are several near-perfect one-season series, like Fullmetal Alchemist: Brotherhood and Death Note, and a few multi-season shows that nail their first chapter (Vinland Saga and Mob Psycho 100 come to mind). For titles that consist of multiple outings, a flawless one in the middle can prove a game-changer. Such is the case for these series, which were good to start but really took off after these strong additions.
3) Demon Slayer Season 2

Demon Slayer Season 1 sells the anime almost immediately, but it still takes time to find its footing as Tanjiro trains and learns the ropes of his new life. Season 2 cements it as one of the greats, delivering a perfect outing of anime from beginning to end. The series’ second chapter consists of the Mugen Train and Entertainment District arcs, both of which raise the stakes significantly โ and ramp up the production quality and emotional heart to boot. Rengoku’s death remains one of the most gutting moments of the series, and the fights against Dabi and Gyutaro show just what the anime is capable of. Demon Slayer only gets better from there, marking Season 2 as a turning point. It’s good before that, but these two arcs elevate it to greatness.
