Kotoura-san as a whole is kind of a mixed bag for me. On the one hand, the character development within the series is rather solid as Kotoura's character gradually changes for the better as she learns to move on from her traumatic past, reconnect with her mother and others among her new circle of friends also get fleshed out. ESP Club President Yuriko has her own parallels to Kotoura in both share a tragic past due to psychic abilities leading them to be ostracized by others and negatively have their family relationships affected. There's also a solid arc in the second half of the series where the ESP Club gets entangled in a mystery involving a series of assaults being committed on high school girls by a mysterious assailant.
On the other hand, the show's comedy and elements to its storytelling do have their bumps for me. For the most part, the comedy to Kotoura-san is used to lighten the mood on the show's more serious themes. While I don't mind the comedy being used to lighten the mood, much of it misses its mark for me since it relies on some of the more obnoxious quirks of the major characters (the perversion of Kotoura's grandpa and Manabe, Daichi's indifference, Yuriko's obsession of using Kotoura's powers for her club's gain) to carry it along at many points and I did feel there were points where it disrupted the serious mood that complimented the show's more dramatic points.
Even the show's serious side does have some issues. Kotoura-san is rather blatant in depicting the serious moments it portrays throughout its run with little in the way of subtlety in doing so. This is rather apparent in the opening half of the show's first episode where it depicts the growing problems in Kotoura's life that lead her to become an outcast due to her psychic powers. The prolonged time focused on building up on her problems is a bit overboard and does make it kind of hard to take seriously in spite of any intentions that the show's creators had to make it a serious one. The blatant approach Kotoura-san takes to exploring the pathos of its cast won't be for everyone, especially for those that prefer drama that is a bit more subdued.
In spite of its flaws, Kotoura-san was still a mostly solid series exploring our female lead's recovery from a traumatic past she had no control over through making friends who accepted her and moving on from the past she suffered from. It is still worth a look if you are into high school dramedy.
