I'm usually a purist with my anime, but I make no apologies for saying this- Robotech is my favorite TV show of all time, and my favorite anime.
I won't get into the whole discussion of whether the translation butchered the original Japanese creators' intentions or not; I stand in awe with what Carl Macek was able to do with 3 distinctly unrelated series, and feel that the whole Robotech mythos is more engaging and fun than the original series.
This is the only show that I have felt such an emotional attachment to, for so long. There is no rational explanation; my wife gave up trying to figure it out a long time ago...
Robotech spans 3 generations of people battling to save earth. It was one of the first American cartoon series to have a continuing storyline, to have character deaths (and births!). It showed racism, interracial relationships, the futility but necessity of war... all in 1/2 hour weekday installments right before school. Plus, it had the coolest mecha around.
I've heard rumors of a new Robotech 3000 series under development by the animators responsible for Beast Wars and the Voltron 3D show. I'm apprehensive but hopeful; I doubt any show can ever really hope to match (and mesh with) the standards set by the original series- identifying with characters may be a wee bit hard with CGI models. But, I hope that it renews interest about Robotech with the public. Perhaps then the snafus that have kept causing Robotech to disappear from store shelves will be overcome. (Anyone for a full DVD set?)
