Writing this, I assume the reader is familiar with Urd and Skuld.
Art was good, like in the TV series. I didn't feel annoyed by the sound, so it was also OK I guess (but I didn't pay special attention).
I think I can't treat "Story" and "Characters" as separete topics here, because they are so closely connected to each other, and they are what makes the OVAs so enjoyable.
These are sweet little stories of friendship and love about my preferred series characters Urd and Skuld. I especially enjoyed watching the suddenly changed persons and how they and their social enviroment responded to the changes of their physical appearances (Urd changed to kid, Skuld changed to adult). This also brought aspects of the unequal sisters to shine which were not seen in the series before.
I liked these OVAs more than the TV series. For me, ep 2 is the best "Goddess" episode so far, and also ep 3 is well above series standard in my eyes.
For appreciation of the characters, it probably helps if you have watched the TV series. Even if you don't consider it that great, I think you can still enjoy the OVAs.
