Feel free for the madness to begin, but for me, its Dr. Stone, with Full Metal Alchemist: Brotherhood (Subbed) in close second.
We will do a poll for the first fifteen or some posts animes, but why I picked Dr. Stone is because I feel that the Manga and Show both keep the show well paced and one second your at episode 1 Season 1 and then the next day your at Season 2. Its amazing too because I feel like the show is at a 10 billion Percent meme rate
