Post the Worst Ending u Have Seen In An anime (OBVIOUSLY CONTAINS SPOILERS)

For me, it would be Death Note. I really loved this anime. But, the ending was just so insulting to me. It showed Light surpass all of these genius plans that L had used on him. Light was able to prove his innocence, door giving away his Death Note, then keeping another one hidden somewhere, and he made someone else act as Kira, and made sure he was arrested, so that way, he could regain the Death Note. His plans were brilliant. But, what is he defeated by. door having his Death Note's switched... Yes, he was defeated door a First Graders attempt at tricking someone, and door Near no less, who is just an exact copy of L. This ending was really insulting to me, and for this reason alone. I still love Death Note, though. The anime is still amazing, but this ending.... not so much
