The Five Star Stories/YMMV


 * Canon Sue: Maximum is one of the few who aren't boring -- mostly because the story isn't really about his Sue traits, but about him.
 * Ensemble Darkhorse: The Cross Mirage, a lowly recon mech that barely gets any fight scenes is quite popular for some reason, even getting a talking gun named after it in Magical Girl Lyrical Nanoha.
 * Because Jhon pilots it? He himself seems to be a fan favorite.
 * Freud Was Right: Check out the details on the Knight of Gold's swords.
 * Jumping the Shark: The Chivalries arc is often reviled due to the introduction of many a Canon Sue, as well as the creation of a Continuity Snarl simply because Nagano wanted MOAR MECHA.
 * Magnificent Bastard: Just look at Emperor Amaterasu's plan for uniting the Joker!
 * Squick: If genderqueerness really bothers you this is not the manga for you. Also, a lot of things the less scrupulous Headdliners do with their Fatimas are definitely disgusting by anyone's standards. In fact, a lot of things about Fatimas are kind of disturbing, really. And let's not even get into the weirdness behind the circumstances of Doug Kaien's birth...
 * If you think that Doug's birth is squicky, just look at Max... Theirs is well and truly Big Screwed-Up Family. Dr. Ballanche didn't even started it.
