So I finished Macross 7 about a month ago and I really liked it. I think it's probably my favorite Macross (Don't get me wrong, SDFM and Macross Plus are better series, I just personally like 7 better).
I didn't really have any problems with the complaints I hear about the series. I can understand most of them, but I didn't find them to be problems. It has great music, I really liked the characters, and even if it's a bit repetitive, I still found it really fun.
I understand the complaint that it gives too much power to music and it's probably my biggest problem with the series, but I'm still OK with it. There's only so far you can go with music as a center-point without either powering up music or dropping it as a focus, and I think Macross 7 understood this. The problem is if you keep music as not being powerful like in SDFM, you just get the same plot of a musician culture shocking aliens told again. There's only so many ways you can tell one story. In fact, this is one of my main problems with Macross II in that it tries too hard to be like SDFM and DYRL and just ends up not being very good. I think powering up music was just a logical step.
