Everyone else has just about said it by now, but yes, the OVA is more fresh than the anime cause of the different change in story direction. And I have to agree it was nice that Sakura was finally brought into the light, since she kind of served as the most minor character in the club and never really had any major development. Noe is an enjoyable sister character, though she also appeared very rarely in the anime. She was mentioned plenty, but also has the tropes of respecting her brother a lot and being bashful about it. The most surprising thing about this OVA was thefast food employee being Takao's mother, though I should have pieced that together earlier and felt kind of silly for not doing so before.

This OVA shines a bit of light on certain characters and makes you realize Sakura is perfectly fitting of being in the club since she's whack in her own way. Of course, they shoehorned in the rest of the club before the OVA began, but the attention was definitely on Sakura and Noe.

Oh, if only Tama appeared in this one. Though despite her absence, I still ranked this higher than the series, so it does a lot more right to me than the original. Maybe cause they visited a different location too, which gave it a sense of freshness.
