These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Senki Zesshou Symphogear
Ass Pull: The revelation that God and the Tower of Babel are real comes right out of nowhere.
Ryoko translates the ancient Sumerian word 'Kadingir' in episode 10, saying it has come to mean a 'tower so high that it reaches the heavens'. The Tower of Babylon was a tower that was supposed to reach Heaven. So there was foreshadowing.
Big Lipped Alligator Moment: The Training Montage in episode 9 of G. It's comes after the revealed that Miku is alive and doesn't seem to serve a real purpose compare to season one's montage to make Hibiki a better fighter.
It serves to have Genjuro and Hibiki sing the theme from Police Story.
At first glance, both Kirika and Shirabe's Gokuren Igalima and Oukyo Shul-Shagana, while decent songs by themselves, don't really come off as anything special. Come Episode 11 and 12, both turn out the layers of a same, epicly rocking song, Edge Works of Goddess ZABABA.
Episode 11 finally confirms that all the spiels he said about 'saving humanity' only equals to 'saving himself', instead of preventing the moon's fall, he instead quickens it while ensuring just his safety and dreams of being the 'last action hero' of humanity.
Yumi, one of Miku's friends who keeps telling how things are played like in an anime.
Even Better Sequel: The majority of the fans who watched the first season found the sequel to be superior after a few episodes had aired, due to the increased action, an antagonist group that has been around since the beginning and most of them are developed Anti-Villain... and compounding them is the utterly depraved Dr. Ver as the Big Bad.
Homage: Though this is in large part because of blatant stealing of plot elements from the well established Magical Girl Lyrical Nanoha franchise. Just about every major event and major character has a direct mirror (Frontier = Cradle, Dr. Ver = Dr. Scaglietti, etc.)
In fact, it's seen as so much better the Blu ray sales for the first volume were more then Double of that of the blu-ray sales of the first season.
Foe Yay: Maria and Tsubasa in Season 2. Not only is Maria's Symphogear identical to Kanade's, their duet in the first episode is awfully suggestive, with furtive glances and both performers stroking their long, phallic microphones. Once Maria is revealed as a villain, she and Tsubasa directly oppose one another, with their fights being some of the most intense.
Fridge Brilliance: If the Noise are behind most monsters in legends, maybe people accidentally fused with relics gave birth to werewolf tales?
Gungnir is Odin spear and he is associated with berserker, making it a great name for Hibiki's relic
Fridge Logic: For some reason the trio forgets to use Durandal to take out the Moon, relying instead in a choral Ultimate Song.
It was destroyed in the process of defeating Finé.
I Knew It: Some fans assumed that the Downer Beginning was just a Troll and that Hibiki is still alive. Some even thought of it already at the very beginning. Boy, they were right!
In season 2, Maria isn't Fine's reincarnation. Also, for all of Ver's seemingly Well-Intentioned Extremist propaganda of 'saving humanity from the Moon's fall'... he just lied his ass off, he just wants to save his own butt and the rest die for his amusement!
Les Yay: Within the first episode, we're shown two girls engaging in emotionally ~intimate conversation while physically sharing the top bunk of a bunk bed. By the second episode, it is implied that such is a regular occurrence for the two, even if it's not meant to last.Scratch that. They reunite and get to see the shooting stars in the end.
Miku seems to be very fond of Hibiki, blushing around her, being unhappy when they can't be together, being reduced to a solemn, morose wreck after her death... Hibiki, for her part, all but confessed her love for Miku in the second episode. While they were sharing a bed.
The first scene we get of Tsubasa shows her blushing while Kanade tells her that she (Kanade) needs her. Following Kanade's death, Tsubasa has been obsessed with Kanade.
Episode 3 has Ryouko biting Hibiki's ear and pretty much (read: explicitly) saying that she wants to take Hibiki's virginity.
Miku checking out a book titled "Be Honest with Yourself". It's not that hard to figure what it's about.
Hibiki's constant glomping on a blushing Chris.
In the 2nd season opening, a naked Tsubasa and Chris hold hands.
Shirabe and Kirika bring this in the second season. Kirika is quick to comfort Shirabe when she's depressed or angry, and they even have a Shower Of Love scene in the third episode. In the fourth, Kirika even holds Shirabe in her arms.
As of the 6th episode of season 2, the Meta Guy, Yumi directly compares her to the lead of a harem anime in terms of how dense she is at realizing Miku was worried she was feeling down and had gathered their friends for an okonomiyaki party. Cue Miku looking both pleased and embarrassed.
In the second season's 7th episode, Miku has basically been acknowledged by the 2nd division as Hibiki's wife. They don't confide to Hibiki's mom or grandma of Hibiki's condition, they confide to her. Genjuro even states that she must protect Hibiki.
In the second season Miku is brainwashed by her love for Hibiki by Ver. Her Relic Song is even clearly a love song about protecting Hibiki
I won't ever let you go./ I won't let you go far away./ I love you this much/ look how much I love you
Can't forget the Fine/fine puns. It's become so wide spread and intense that some people automatically read fine as Fine so long as the subject is Symphogear.
Moe: Hibiki and Miku definitely qualify, and Chris has her moments. And, come season 2, Kirika and Shirabe are both on the Moe bandwagon.
Moral Event Horizon: So how do you think Ver can top Fine in terms of being utterly despicable? Well, a good starter sign of skirting the line would be when he fetches Noises on passing by kids just because they were looking at him fetching Noises to US soldiers with a smile on his face. If that wasn't enough, then forcefully injecting Psycho Serum to Kirika and Shirabe and tells them to use the Swan Song (which would mean death for them) while acting like an Entitled Bastard despite their pains and dangers of getting injected with them would be him crossing the line. Kidnapping and brainwashing Miku into giving her a Symphogear form? Now that's leaping faaaar away and deeper from the horizon, accompanied with the biggest "WOO-HOO!" you can ever imagine. He's still waving and taking another leap when he sends Nastassja off to the moon, killing her, because she's trying to avert the damage he's caused, this is also the final push for Maria to finally have enough with bearing with him and deciding to kill him.
Narm: The show's detractors are prone to noting this.
Narm Charm: But, they're not too far off. And the Narm is a large part of what makes the show work.
For both tropes, special mention goes to Finé/Ryoko's Engrish.
