overall, the anime was verry good the characters development where somwhat interesting and the show got me relly hooked but the last episode fealt rushed, lot of scene where re-use. A lot of informations where skip and not explain much, not in the sence of a cliffhanger for a season 2 ( lets be honest, after 11 years, there probably wont be one) but relly more in the sence of " go read the manga if you care about that" wich relly is a disapointing for a last episode.
beside the ending, the anime itself dident feal rushed, the story progressed at a satifying speed, some episode somewhat fealt as fillers but still progress the story, there are somme innacuricy there and there that break the immersion sich as implementing a 20 century japanese concept into a 19 century british school in episode 10 but hey, who am i to juge, its an anime after all.
