I have watched the entire series, and I can tell you quite honestly that there are really only about three good episodes. One is among the first five, the second is the mid-season episode (around #25) and the other is the second-to-last.
Believe me when I tell you, the show is crummy. It does have its moments and SOME charm, yes, but by and large it is pretty stinky. The show has a lot of promise in the beginning, then by episode 8 or so its starts to become monotonous. At about #15 it starts to show promise again, but quickly starts sliding back downhill. Then there's that one good episode at about #25, then nothing but drudgery and outrage and lameness until the second to last episode. And then, thankfully, it ends.
Believe me, I am no Macross hater. I loved the original show, the movie, Plus, and even have some fondness for Macross II. But Macross 7 was truly the bottom of the super-dimensional barrel.
