Also for your whole “mixed bag” thing, that maybe for people like you, but people like me see it differently
I’ll use for Fullmetal Alchemist I’ll try to nutshell it as best as I can what think is a “mixed bag”
There was once a slave named Van Hoenheim who made friends with a homonoculus creature who used him to create a full body of his own and grand him and Hoenheim made a tragic mistake because the creature did it by eating all the souls in the city he lived in
Thousands of years he lived alone until he met a woman she loved, they got married and had two beautiful baby boys. Edward and Alphonse Elric
But the monster that he unwittingly made a pact with came back mimicking his form, threatening his family and town near by. He had to leave
The boys loved their mother very much, but at the age of 5, their mother died of an illness.
Then the boys repeated their father’s mistake by trying to play god, they used alchemy to attempt to conjure their mother back to the living
Edward lost his left arm and right leg
Al’s soul trapped in a suit of armor
They were taken in by Winry’s grandmother
They later great up to be the youngest elite state alchemists, under a kind but brash superior Roy Mustang, and his partner/love interest Riza Hawkeye and the wonderful Husband/Father Major Hughes
One mission, they were sent to investigate a single father who was a scientist, only his daughter and dog to keep him company
One night during their stay, they saw the most horrendous thing. The father out of his mad idolatry of science fused his own daughter and dog into a Chimera, and before that his own wife
This SHOOK the brothers
later on dead government projects of such sickening magnitude followed. The danger the brothers and their superiror get into worries Winry, the girlfriend of Ed, and Riza over Roy
One point Winry tried to kill the one who murdered her parents, but Ed had to restrain her from become a vengeful miserable soul, she stopped but not before breaking down into tears of frustration and anguish
After horrendous discovery after discovery the brothers find a conspiracy lead by the monster that ruined father’s life who goes now by the name of “Father” with his 7 Homonculi children
one of them Envy, under the guise of Hughes’s wife SHOOTS HIM DEAD leaving his daughter and child ALONE
Countless of people are murdered in Gluttony’s rampage
in the final battle Ed slays Father and saves the down, and gives up his ability to perform alchemy in order to gain his brothers body back, after his brother gives his life to give Ed and whole arm.Ed makes amends to his father who now finally over his shame begs for forgiveness for not being there for them when they needed him the most. They both made it after the horror’s they have witnessed, and Hoenhiem could finally die meeting his wife in the afterlife knowing his children are happy
And they return home, where Winry welcomes them with open arms, Ed and Winry get married and have a few children of their own.
The Brothers, after all that hell, had a family again.
I ask you this, after all what the brothers went through does that sound like a “100% unambiguously happy” ending to you?
