I have finally taken the time to watch the last four episodes of this show, and it is one of the very few series I have seen recently where the ending perfectly suits the series. It has a sad undertone — which is evident throughout (by concept as well as by execution) — and quite cleverly avoids the mistake of having to have a “big bang action finale”. All throughout, the artwork is very good and pays huge amounts of attention to tiny details.
Recommended, but beware of the leisurely pace.
