I figured out why it's boring at first. In the first story arc they're just showing off the transforming robots (admittedly, the best jet-into-humanoid design ever). But it's basically a space opera with some teens.
They haven't gotten to the part yet where they discover that their secret weapon against the aliens is a POP STAR who sings trite disco-fluff and PUBLIC DISPLAYS OF MALE-FEMALE AFFECTION. The most powerful armada in the galaxy. Undone by music and love.
As we, humans, especially little teenaged boy humans, are also undone.
When the "Minmay Effect" first appears is when the show really gets genius.
