It’s my least favorite of the three, and that seems to be the general consensus (thought obviously not the opinion shared by all).
However, if you’re interested in Robotech and not just Macross it is a vital link, and contains a large part of the over-arching Robotech storyline.
In any case, it starts off a bit slow and gradually improves. I always felt the series really came into its own around the time that the Zor clone was recovered by the SC (around ep 9-10). So I say give it a chance, but don’t expect Macross.
