In short, the OVA was lacking in too many needed points to be worth watching. Both OVAs appear to be teasers for a possible anime series, or movie, but neither ever appeared. It looks and sounds good for its time, but the story is poorly written - unless about one third of it simply was cut or lost. Negligible background, practically no character development.
An object of interest came to the main characters attention, they tried to get their hands on it, proved to be largely inept, but they possessed a 'unique' (and childishly over powered) ship - for no apparent reason - and were saved. End of story.
It could have been quite good, and that actually makes the finished product seem worse. You would need to be a 'completist', or willing to watch just for the titular ship - which is quite a good design - to enjoy any of the three OVAs. One of the characters is known by two of the other characters, to be a 'manufactured human' of some sort. But they do nothing with this story element. I have not seen any mention of a manga or light novel series as yet, so I still wonder why there were so many holes and undeveloped elements in the finished product. Again, I suspect that it was intended to be the start of a larger story that just never happened.
