I liked Oscar Pill and the whole created universe with great imagination by its author. But I was a little disappointed by the end, because I felt that it was too soon curly, there was almost a hurry that the story ends, that passages were a bit sloppy, not enough worked. A shame as this saga was really nice and addressed issues related to the process of adolescence with some realism, while being well integrated in the extraordinary adventures of Oscar and his friends. But then I see this with my adult eyes and mother, my son he was quite satisfied with this last volume, and regrets that the series ends permanently!
