OVA is pronounced as the plural of 'ovum'? Which is Latin for 'egg', which might be strangely appropriate, given the reactions so far.
I just watched the OAV. Online, with the English dub. All the mecha were cool, as were the fight scenes.
Not happy with Jun's look. Especially when they show how she's dressed off-duty. Jun's attractive, not slutty. Let's not get into her costume (or out of it, for that matter).

No real personality to the faces, or even to the team. Joe didn't so much smolder as sort of sulk, it seemed. Not a lot of angst. Yeah, the smoking was rather dumb.
Leader X as giant eyeball. I prefer the bird-head. You could at least imagine that it was a disguise ('Pay no attention to the extremely powerful extraterrestrial behind the curtain!'). Now have mental image of the Science Ninja Technique: Eye Poke!
Dr. Nambu was only the worst-dressed of several badly-dressed people. And that's without the hair.
