Erased

Erased (僕だけがいない街, Boku dake ga Inai Machi), based on the manga of the same name, is a psychological thriller anime that aired from January 8 to March 25, 2016.

Plot
Satoru Fujinuma is an aspiring mangaka from Chiba who has a unique ability called "Revival" which allows him to travel back in time and prevent people's deaths. When his mom is murdered, he is sent back in time 18 years, granting him the opportunity to prevent his mother's death and save his loved ones from a notorious serial killer.

Why It’s Worth Believing In

 * 1) The anime is largely faithful to the manga it's based on, following the story closely.
 * 2) Exceptional voice acting in both Japanese and in the English dub.
 * 3) The atmosphere is very dark and chilling, effectively utilizing a psychological and mysterious tone, while also very hopeful and wholesome.
 * 4) Plenty of sad and emotional moments that drive the plot and emphasize the dark tone.
 * 5) The portrayal of Akemi and her abuse toward Kayo is frighteningly realistic. Despite being a sub-plot, it is essential to the story and gives a full view to Kayo's life.
 * 6) The intro, "Re:Re" by Asian Kung-Fu Generation, and outro, "Sore wa Chiisana Hikari no Youna" by Sayuri, are very emotional and fitting for the anime's plot and tone.
 * 7) Gaku Yashiro's reveal as the killer is very unsettling and eerie.
 * 8) The animation is astounding.
 * 9) Satoru transitions over the course of the series from a reserved, timid, and insecure person to a confident, strong-willed person who receives love and kindness from his friends and family.
 * 10) The rooftop scene is very suspenseful and intense, with Satoru finally getting to Yashiro and revealing his true motivations and outlook.
 * 11) The ending, despite its flaws, is very heartwarming and positive.

Bad Qualities

 * 1) Yashiro’s backstory is omitted from the manga, giving him little depth or explanation for his actions.
 * 2) There were some rather obvious clues as to the killer's identity beforehand, making the show less mysterious than intended.
 * 3) The ending received some criticism, as Kayo doesn't end up with Satoru, but with Hiromi instead, despite nothing indicating a romance between the two beforehand.

Reception
Erased was met with a positive reception. It holds an 8.5/10 on IMDb and a 100% on Rotten Tomatoes.
