Frankly, I thought that Plus was garbage, but it takes all kinds:

The first scenes are nothing short of enchanting, but what ultimately stays with you is the entirely human story: the characters have all given up childhood dreams of some sort – only to realize, in their hollow adult lives, how deep a part of them those dreams were. The resonance – and the extreme sorrow – of this situation is one any adult realizes, eventually: that the true promise of adulthood isn’t the realization of dreams, but the gradual shedding of them, until all that’s left is routine and draining. This is the part of Macross Plus that sticks with us. The reminder of sorrow, and what we’ve lost.

After that, one would wonder if I didn't like Plus because I fulfilled most of my teenage dreams (my childhood dreams were too idiotic to fulfill: like operating an excavator for a living), and I'm working on new ones. Well, pool Celeste, then. But perhaps not. I still think 08th was a better take on the same basic story by any yardstick. In was a series though, perhaps it was just easier if you have a whole cour.
