This is such a powerful and moving anime that deals with the effect of the loss of a loved one and how much it can deeply change us, young or old. In particular, the anime focuses on the effect of Menma's death as a young child on the 5 remaining "Super Peace Busters" group and it's very interesting to see how much her death has and, more interestingly, not changed this once close group of friends. There is an incredible driving force of guilt and jealously that permeates throughout the show, and so this anime is ultimately a story about the journey to resolve these emotions in order to let Menma rest in piece. A lot of the characters may not be completely likable in certain ways due to each one having every obvious flaws, but all those serious flaws interacting with each other are the times when the anime shines best. This is definitely a roller coaster of emotion (perhaps some tears along the way) but I loved the ending which resolves things very nicely. This is a touching story and a can't miss if you're interested in a more dramatic and moving anime. Watch it!!
