Psychological Thriller, Supernatural, Detective Manga Status: Complete | Anime Status: Complete

It has no filler, a phenomenal English dub, and an ending that is emotionally satisfying—something many long-running series fail to achieve. Manga recommendation: The manga by Hiromu Arakawa is the definitive version. The art is clean, the action is easy to read, and the bonus comics at the end of each volume are hilarious.
