I think Hollywood would do just fine with Macross simply because they won't have to write around or write in a love story. The only audience that matters, the date audience, already has everything they need. The rest of it would be fine if kept looking like it should.
As far as the trailer goes, I think as a premise for how Macross could look, it worked fine. There's just too many of you here who don't see past black and white.
