The only reason why this show got cancelled is because it wasn't promoted as well as the Transformers was.
I think COTGB had a lot of potential and was really one of the more undeappreciated shows of the 84-85 TV season. If it had lasted longer than a year I don't think it would have made too much of a difference if it got cancelled one way or the other.
I think they should bring it back at least to TV so that it may be preserved as one of the better shows of the 84-85 TV season. Long live Gobots.
