So Persona 3 the Movie 3: Falling Down quite early on time skips a bit where SEES are facing off against Strega and having defeated the last of the Shadows, but comes an early plot twist that just changes so much of what SEES were initially doing that it changes the course of many of the core cast.
Makoto's beliefs is struck once again but this time not wanting to keep the Dark Hour and playing hero but having to protect those close to him and not for him to get hurt if they were to "vanish" thus keeping his distance towards SEES, a new character arrives in the form of Ryoji Mochizuki voiced by Akira Ishida (Hmmm..same voice actor as Makoto) and quickly becomes buddies with Makoto and the rest of the SEES and being quite the womanizer as well, anyways he helps Makoto get him out of this funk of keeping his distance from people and even getting Makoto to join the "Helper's Club" to earn a few bucks. The second core plotline comes in Junpei and one of Strega's, Chidori Yoshino voiced by Miyuki Sawashiro as Junpei starts to care for her even though she's an enemy and they actually get in a relationship together while Chidori is recovering in the hospital. The last core plotline is in the form of the aftermath of the early plot twist LA mentioned that actually gives Mitsuru development and world building, not only about the Dark Hour and Tartarus but at the same time is linked somewhat thematically to Yukari as well. These three core plotlines deals with separation through death one way or another, Makoto's fear of losing any of his friends, Junpei and Chidori's relationship near the climax and Yukari and Mitsuru dealing with death in their own way and thematically Persona 3 the Movie 3: Falling Down does a good job executing it.
There are some some smaller plotlines that gets resolved in which they were kinda brought up in the previous movies, such as giving finality towards Fuuka and Natsuki, Akihiko's resolves on why he still fights and some more detail into Aegis as both a character and her obsession with protecting Makoto gives some clarity.
Once again, like Midsummer Knight's Dream, Persona 3 the Movie 3: Falling Down gives some cameos to social links, this time towards the student council concerning Chihiro Fushimi and LA brings up the social links again as Falling Down seems much more focused on it's social link aspect than the dungeon aspect from previous movies, kinda makes sense due to the formulaic Shadow hunting is done and gone so what else can they do?, so LA sees the focus to social links to be an obvious direction this movie would go to, especially concerning the core SEES members and their interactions with one another and they do the social links events as well, the biggest example being the Kyoto field trip and the *ahem* Onsen operation.
LA won't say much again about the production value as it's the same as Midsummer Knight's Dream, with it done by A1-Pictures and the voice cast is pretty much the same just with Akira Ishida and Miyuki Sawashiro pulling double and even triple duty with some of the newer characters. But with the animation department, LA will say it is the same as Midsummer Knight's Dream, the animation is consistent and the character designs are the same silky designs with the action packed battles the same as well. Consistency was what LA wanted and it easily passed.
So Persona 3 the Movie 3: Falling Down did ALOT, mainly due to the change of pace and how grim dark it took thematically, developing the majority of the cast along with it and executed rather well, it helps that the core cast almost all have the same themes of losing people and death being prevalent to them happen to them, nonetheless if Midsummer Knight's Dream was the build up to it's themes and it's characters then Falling Down is the climax of it all. Sure this movie rushed it rather early but LA can give Falling Down some grace for at least trying give characters much needed screentime, character development and tying itself nicely and thematically linking itself to it's themes of death and separation was dealt with extremely well.
And now we see the "final boss" as it were...
Fall lies in wake of the Winter of Rebirth...
