I agree with Gubaba on this one. Macross is a geek series and always has been. Macross Plus is about a serious as Macross ever became, but even that OVA was solid sci-fi geek porn. Macross is not the kind of show that caters to the main stream, especially North American audiences, and is not cool nor will it ever be. Even the hip, much lauded Cowboy Bebop isn't cool to most people simply by virtue of being sci-fi, animated and foreign. And like it or not, the rule of cool still reigns over the opinions of the masses. Our geek shows, no matter how accepted and popular, will always be geeky and never cool.
I say just be thankful Macross Frontier rocks. It's great Macross, or what a Macross sequel should have been. Enjoy it while it lasts
