Why I think #AttackonTitanFinalSeason OP is good:
Whether you dig the song or not, that is entirely subjective. To me, it fits perfectly with the visuals, highlighting the grandeur depiction of war and sneering at it with its ominous vibe
In a black & white dominated visuals, the explosions are portrayed in full colors - unnaturally so. They're "given" these colors by men themselves, as a metaphor for giving their dull-colored worlds meaning
We can see the spine building up from the explosion - violence breeds life in retaliation & hatred, which then manifests its own form (also a clever foreshadowing I believe)
Explosions in reverse colors - a smart method for reusing animations AND showing there's always two sides to one's actions - violence can be a mean to end violence, but is also inherently tied to breeding it
Colorful explosions yet again, bringing colors to people's dull lives in which the means to let out their hatred became their way of living
Flame of violence burning down everything on its way, depicted by filling up the entire space of the next frame
Birds - symbols of freedom having burned from the fires of violence the people ignited fall to the ground. Violence sprung from people's sick nature makes them unable to fly
Grandiose depiction of war's absurdity - sporting unnatural poses the soldiers march to the flashy music
This sequence right after further highlights that absurdity. What was meant to come off as 'grand' is subverted by 'comparing' soldiers to birds - symbols of freedom - and how much off the mark it is.
People crumbling may be literal, but may also serve as metaphor - what we destroy, in turn destroys us too
Every action of violence or a mean of letting out hatred creates ripples in the water, which later can turn into storm
Finally, ending with the shot of a certain Titan - the personification of violence and hatred given its form by the people's need of creating a scapegoat to blame for their own wrongdoings
+ as if this OP couldn't get any better. In addition to the lyrics, those ominous lines are chanted during chorus. The second one is even a reference to chapter 131 of the manga
