Death Note
It took me almost two months to finish watching this (for comparison I finished 3 seasons of AOT in just 3 days, Jujutsu in just 4 days, etc) cause I found some episodes were really boring so I just went on w my life and totally forgot about it except bro what the fuck is up with the last 12 episodes and tbh especially thE LAST 4 EPS?? They made me keep thinking and guessing fr and honestly those last episodes really saved this show from my very high expectation 💀💀
Also I didn't even expect the ending would be like that (lowkey spoiler alert) based on the title of the last episode
