I was pleased with visual quality.
We had an overview of light and heavy sides of the story. But I think non readers might be somewhat lost. Afterall, it's a bundle with recent volumes, so it's not really a problem as the vast majority of buyers aren't new to the story.
I was waiting for the character managing the house (sorry, no name as it would be spoiler already I think). It was short but I liked it, even with the gag drawing style of the manga author.
Good fanservice intro.
Edit: too bad it's a short OVA. There's enough material for 24x23min show. But maybe they judged the audience isn't large enough.
