Talking specifically about Jin-Rou, though, I will start with the good.
The animation quality, especially with facial expressions, is insanely good, almost scarily so. The first act of the plot is compelling and paced extremely well. But that's about it.
The bad is almost entirely plot and character based. The main issue with Jin-Rou is that our main character, Fuse, has absolutely no character arc; the vast majority of the movie focuses on his feelings or lack of feelings of guilt after a certain event in the first act, but after what feels like a bunch of filler, he ends up making a decision at the climax that just leaves everything unresolved. While it is probably a valid argument that this is one of the main points of the movie, I can't accept that in good conscience when the story itself is ultimately a very generic dystopian world, insurgency-fights-it deal. If Fuse has to be a statue of a character, then there MUST be a compelling plot past the exposition and a great climax so that my time isn't wasted.
So essentially, what Jin-Rou provides us with is a rehashed, almost creepily mediocre story everyone knows and no characters worth any emotional investment in. The artwork, sound design, and first act are all very well designed, but all that is dragged down by a pitifully forgettable (and I have done my best to forget it) plot and cast.
How this is almost an 8/10 average is eons beyond me. I would only recommend this to aspiring animators as a case study in how to effectively animate facial expressions and small movements, and to aspiring editors/directors as a case study of exactly how NOT to make a compelling story that can express an idea/theme.
For me, I give it a 4/10. It's not worthless, but it tries its best to be.
