Ueno-san wa Bukiyou is an anime that has an ok setup of Ueno always trying to get her kouhai Tanaka voiced by Aimi Tanaka into romantic and sometimes crude fanservicey situations for the attention and whatnot and 10/10 Ueno's own inventions or her weakness to romance backfires on her. Now LA will say the crude fanservicey moments does make some squick towards the humor, like Ueno trying to make Tanaka drink Ueno's distilled piss (seriously) to making Tanaka eat her panties that turned edible, that is the level of "crudeness" the humor comes in, of course the comedy does fall under slapstick, majority if not ALL the time falling under Ueno. So the comedy is ONLY utilizing that formula and goes somewhat extreme with it but not much else other than that as a whole.
The animation done by Lesprit has a pastel moe aesthetic to it and it suits this kinda anime short and especially towards the character designs and for such an anime short, it does itself well with the facial reactions, especially coming from Ueno and her wing-woman Yamashita voiced by Akari Kageyama albeit chibi-comedicially of course.
Voice acting wasn't that bad either with Yuu Serizawa as Ueno having great cadence as Ueno from the confident tsun to embarrassed dere, LA was actually surprised that Tanaka was voiced by Aimi Tanaka. The minor cast also gets a mention from several well known voice actors such as Rina Satou, Shiori Izawa and Miku Itou coming in to play bit parts and blending well with the main cast.
Ueno-san wa Bukiyou for a comedy anime short does what it sets out to do, crude fanservice yes, but for it did it was fine...barely for what it did. Obviously not the best anime short of Winter 2019 but...it was an "interesting' anime short with some chuckles here and there, mostly in the situations Ueno goes through.
