Anime Up and Down

The up part is a show that is becoming the best vacation from seriousness I've found, Keroro Gunso.

On the other hand, down is too trivial a description of the at times crushingly sad Blood+. The series is well scripted and produced. The mood is sometimes warm, involving, heart-breakingly so, but often vicious, and explosively violent. Every episode shows what can happen to ordinary people when they become the targets of more powerful agencies that are absolutely sure that what they want is right.
