This is more like a brain-work anime than any action.
So although it does show bits and parts of a fight between some immortal dude and a busty ghost swinging a metal beam around, it's clearly not the focus. In fact, the only reason that's there is help them make sure she actually disappears when they do what they need to. [Continued in replies]
[#1] Just a distraction. And I do agree the pacing of this anime was terrible, whereas usually, this kind of anime would have one or two enemies to fight prior to the main end villain, they seem to have forced the final one to go on as long as possible to fill the lack of another arc. I doubt it's the animators fault, source material was probably lack luster to begin with.
Source materials pretty good, and there are 2 or 3 more arcs after this. Though I always wondered how they were going to do this part because there's just so much pure dialogue in this arc that it would be difficult to adapt.
There r only 3 eps left, so if didnt, then there would just be 1 or 2 random, unrelated eps at the end which having is frowned upon in creative communities. Also, this is mainly of mystery genre, not thriller (suspenseful) or action (combat) or psychological (mind-fucking), meaning it has a lot of what u say is "so fucking boring" because the basis of the entire genre boils down to 'talk-no-jutsu' if u dont have a significant emphasis on the other aforementioned genres
3- How about rather than complaining about it, aka crapping on a bunch of peoples' hard work and blood, sweat, and tears, u find something good to say instead, and ONLY say that.
Pretty sure U would get pissed off at someone saying such about ur work.
P.S. this one is more for the other bashing comments rather than yours as it was much more polite
1- NEVER watch One Piece! After the first season and not including fillers and prologue/introductory arcs to main ones (e.g Drum Island, Little Garden, Jaya Island, etc) then ALL main arcs r between 20 to 50 eps long before timeskip. Afterwards ALL non-filler arcs r about 50 to 70 eps long, exceptions of Dressrosa which is nearly 120 eps and the current and thereby incomplete Wano Country.
4- Instead of JUST saying something "has potential, but...", u should provide some kind of constructive criticism, even if the creator(s) can't see or hear it.
Not ONLY pointing out wats wrong about something (thats just regular criticism and more often than not tends to rub people the wrong way) but to also provide some form of fix or solution to the problem, such as "'this arc is far too long', so i hope they dont just end the series at this is season and the next one isnt as tedious."
5- If ur problem that r referring to is having to consistently pause in order to read the subs, then dont watch the nearly pure mystery genre animes as anything BUT dubs, as u can (obviously) not worry about pausing for you can better keep up with the 'talk-no-jutsu' since it will be in a more native tongue of yours that japanese (i dont know what ur native tongue is but i assume english, the sub language, is either 1st or 2nd fluent language, maybe 3rd, idk)
Damn Iwanaga is really good at coming up with theories, though near the end there it seemed like Rika had the upper hand...
I've been trying to think about it and what if the father's killer wasn't Karin but her sister? That diary sounds way too convenient to be true imo, maybe the sister was jealous of Karin's success and this was her revenge?
It's also possible that the dad died accidentally and the sister came up with the diary entries to try to point fingers at Karin...
