I felt the ending was maybe... missing something. I think that it might have been a little better if it had suggested at some kind of future for all of the students, rather than simply ending
You have to admit though, it really is pretty much what you'd expect from the author given his other works............he really does leave a lot at the endings up to the readers to decide. I personally like that type of endings oftentimes.......but it's a style, yeah, and not everybody likes that style nor are all stories suited to it either.
