The story, the weakest link in so many "good" anime, is excellent in Kill la Kill. Plot specifics aside, not a single episode of the show is pointless "filler" or is ever disrespecting the viewer by wasting their time. Kill la Kill effortlessly portrays amazing scenes of every tonal variety, while never deviating from the point of story, which is to progress the plot. Kill la Kill's plot itself is very unique, and while is draws elements from the older Shounen manga and anime, it makes sure to do it's own thing. It succeeds in taking "fanservice" and turning it on it's head, transforming it from a shameless attention grabber, into an integral and interesting part of the story. The plot is phenomenal, in that it has a very interesting premise, and it's progression is never hampered, never falls for bad tropes, knows when to take itself seriously and when not to, and always has something interesting happening. There is never a tired moment in Kill la Kill.
Yoshinari Yoh and the other key artists really outdid themselves in Kill la Kill. The level of effort put into every episode cannot be understated. Every frame is hand drawn, and even when CGI is occasionally used, it's on hand-painted backgrounds and with immaculate visual effects that blends seamlessly into KLK's visual style. All the artwork done in KLK culminates into Trigger's hallmark stylistic look, with character's, action, etc. always looking very crisp and holding a very high bar for standards. The visual style never deteriorates and in fact only gets more rich as the show progresses. Older teen girls fighting in supernatural power-imbued scanty sailor uniforms has never looked this good.
As with everything in the show, the sound design in again, excellent. A superb original soundtrack by Hiroyuki Sawano complements atmospheres and characters perfectly, with a great mix of of genre and types. Also of note is his clever incorporation of classical music tracks into scenes in a way that feels very natural. Overall not much to say in this section, other the sound composition and magnificently executed, and you should experience it for yourself if you haven't already.
Characterization is one of KLK's strongest areas. Characters, including the side ones, never feel like an afterthought and all given development and are fleshed out. However the main characters are naturally given the most development, and as such are some of the strongest and most memorable of any television series. You come to able to understand and empathize with all of their different struggles and ideals, and simultaneously receiving a highly enjoyable visual spectacle. Characterization and exposition never feels like a boring "learning tax" just to be able to understand the character's motivations. Everything is done fluidly and in a way that makes you even more enamored with the show and characters themselves.
In terms of "enjoyment" or the "feel" of the show, it does even better than one might expect. The show never resorts to pointless, or 'low brow'/shameless fan service to keep you interested. It's merely a bonus that is also integral to the plot. The characters, stylization and visuals, the music, and never knowing what's around the corner in terms of the story all coalesce to make the show extremely enjoyable while never stooping to cheap tricks like filler to extend it's overall length. KLK is about as close as it gets to pure anime good-ness, where every episode has memorable moments that are fun to remember.
Overall the Kill la Kill is as close to "perfect" as an anime is able to be, as of end-of-year 2020. It executes all the individual components that make a good show immaculately and it's reflected in the finished product's quality. If I could only watch one anime series for the rest of my life, I'd have to pick Kill la Kill. The genius of the creators and hard work of everyone involved in making the series really shows, and I highly recommend watching the behind the scenes documentary for Kill la Kill after completing it. If you haven't watched it, you're missing out on the greatest single-cour anime television series to date. If you have, you know what I'm talking about, and I implore you to rewatch it after watching the behind the scenes of Kill la Kill.
