I'll go ahead and say it: anime is hugely addictive. I don't mean that in a bad way, either — from the moment the first episode of a new series completely grips me, I want to consume as much of it as possible.
In general, anime have figured out a winning formula that blends archetypal, classic storytelling with cutting-edge action and visual craft, and it's why IPs such as One Piece, Jujutsu Kaisen, Solo Leveling and Demon Slayer have continued to do well.
