Naruto
[spoiler] I stalled on Naruto. After the Pain Arc, Naruto got really weird. The story elements with Sosuke were still interesting, but having Naruto becoming this conscientious objector pacifist, with Sakura falsing declaring her love him. I dont know, it got really weird. Bad weird.[/spoiler]

I've never understood the concept of spoilers. I dont see how knowing something in advance, can ruin something for you. Its like claiming that knowing how a magic trick is done, ruins it for you. Why? Now not only can you now appreciate the spectacle but now you can also admire its craftsmanship. I also dont think spoilers really exist. Even with a basic understanding of story structure, and fiction tropes, you can accurately read 'script', and know what's going to happen. This wont prevent you being surprised either, or make you not enjoy the show.
They also make threads like this annoying as well.
