Just downright hilarious! I think Hinamatsuri's strongest points are the character's in this series and its writing. The characters are all somewhat opposites, so there interactions usually result in amusing dialog. Hina is very deadpan and lazy, Nitta is narcissistic with a soft side, and Anzu goes from hardheaded to incredibly sweet. Just honestly do yourself a favor and watch it!
If I had to pick one weak point, it's the story. The overall story is a little muddied and it can jump around a lot. I thought that we could use a little more backstory about the girls, and also that last episode of what's going on.
