Oh, I get where you are coming from in regards to the romance in this series being flat. I actually thought I had made that clear.

It's extremely shallow and the reasons given for the romances are extremely shallow as well. That distinguishes it a lot from Macross Frontier where you could follow those people falling in love and recognize why it happened.
Of course I am not going to agree on Sheryl and Alto being forced together. But I think we've been through that discussion enough to not repeat it here.
Kagura going all mellow of a sudden is another point which came out of nowhere with no good explanation for it. Well, I guess he might have recognized Zessica for a much superior mate than whiny Mikono.

But still, man, what a way to wuss out.
