I'm a heartless monster.
Grave of the Fireflies, 6/10.
Had some very good scenes, but the intended message ultimately was the damning factor. I do understand the point to be anti-pride, but there wasn't much in the way of conflict between pride/no pride, and the end result was largely frustration with Seita rather than sympathy. There's a line where pride stops being pride and becomes stupidity, and after crossing that line it becomes very hard to empathize with Seita, especially when he's consistently taking the wrong path. The major detriment isn't that he makes mistakes, but because there's no good argument made for why he's making the choices he does beyond an overtly vague "pride". Because we aren't given enough breathing room to look at how he became so prideful nor even posing reasonable justification for his behaviour, the message ultimately fell flat for me and left me wanting to punch him more than anything.
That isn't to say his actions were unrealistic, I can believe a person his age might act that way. More specifically, I had a problem with the narrative construct of Point A to Point B. There wasn't enough connective tissue vetween one action to the next.
All that aside, I did feel sympathy for Setsuko and many scenes were absolutely heartfelt. Despite Seita's poor execution, it did manage to well up some solid emotion. So I can't call the movie bad as much as underwhelming and not quite up to task with what I hoped for.
Update: On further investigation, I like Seita less. I looked into how the author created Seita and found that it was largely an apology to his real sister who died under basically the same circunstances, him being essentially Seita. I knew all that, but what I discovered is that Seita is also a combination of how he acted with fantasies of how he wished he acted implanted, namely that in the film Seita would bring his sister food but in reality he had scavanged for food but impulsively ate it instead of sharing, and immediately felt remorse and eventually resulting in his survival and the death of his sister.
Making that kind of change isn't necessarily an inherently bad thing, but that's a very shitty way of apologizing. The character representing his bad choices gets sugarcoated to being a better person amidst an apology for sacrificing his sister to survive. That's bullshit.
