No, actually Super Dimensional Fortress Macross was originally about making fun of Gundam and some other robot animes (witness the "falling into the cockpit" parody that was its first couple episodes). Then it was about making fun of the stupidities of Space Battleship Yamato and being ridiculously awesome. The music is a multi-series plot tumor resulting from having to give Minmei a reason why she could ever be of interest in comparison to lady Hayes. 
The love triangle threesome setup is, at its best, highly subjective. Sure, I can see how you got that, but most people I've talked to see a clear Sheryl win ahead of it in the probablity rankings.
The use of singing as a battle tactic and the Jammer Birds/Sound Force come to mind from 7, and it's never quite recovered from that. Frontier is gleefully unrehabilitated, a giant step backwards from Zero.
The original conception does not necessarily matter compared to how it eventually ended up.

And, my god, Zero was terrible. It started out good but then... bam, terrible!
Plus would technically be good, if all the characters weren't such douchebags.
Yeah, god forbid that the first episode of a show that premiered on the 25th anniversary of Macross includes a few callbacks to the original. 
You don't even know what the plot is about, I bet.
No I can't say I do. The series hasn't been released in North America.
All I saw was some city fight with some Valkyries and some whatever aliens and I thought "oh, this is the part where Hikaru saves Minmei. He's going to fly up, his arm will get shot off and then he'll pull her into the cockpit" and then what happened? Oh exactly what I predicted. Except instead of pulling her into the cockpit he ejects from his fighter on a bungie cord, grabs her in mid air and then the cord retracts. What the hell is that crap???
And the aliens. Well, see the thing is if they're doing the same story, which, essentially it looks like they are. Then having some "creatures" instead of the Zentraedi is kinda lame because instead of having any sort of morality like "we're fighting aliens that just look like humans" they're fighting some monsters and no one cares if they get slaughtered.
So basically same story, but crappier, from what I can tell.
I'll give it a chance when it hits North America, I'll probably even buy the thing. After all I've seen every other Macross except Macross 7, and I own most of them. But the latest one I saw, Macross Zero was pretty much crap. Frontiers look very good, but it looked like what I already own so . . . if that turns out to be case in full I'll be disappointed.
The series is never going to get released in North America. There's a huge rights kerfluffle over it. And the main character can fly. He's got this whole flight-suit dealy, so it's less stupid than it looks.
Yes, Zero had the worst ending in the world.
Look, the evil bug alien thing is actually handled pretty well. They aren't Zentraedi, and how they're dealt with is somewhat different, but it's not like the show considers it okay to kill them just because they're evil bug aliens. They actually get some characterization, despite being aliens. It's one of the biggest sources of drama in the show, where there are people who just want to kill the bugs and those who... don't.
Hell, there's even a big-ass conspiracy in the shadows.
Hell, even the whole combat singing thing got a bunch of strings attached.
Stuff like this only really becomes apparent like ten episodes in though. It's kinda bland before that. Not bad, bland.
It's rather annoying that most series with "realistic" walkers always assume that they are going to replace tanks, instead of simply filling a specialized combat role.
I rather like how MGS4 did it. Walkers only around twice the height of a man, deployed mainly within combat areas, and they serve the specific role of anti-insurgent warfare. Mind you, they were absurdly maneuverable.
You're confusing the "real robot" genre with "realistic robot". Real robot shows merely handled mecha as another weapon platform, but at heart (mainly due editor/producer interference and fanwank) were still initially "kidshows" and later on retained a lot of these aspects because producers needed the gimmicks to sell the show.
However there are a couple of "realistic" robot shows out there: Gasaraki is a prime example and the GITS mechas are the ur-example.
You forgot Patlabor.
