Opinion & Informal
Art: 7/10
The art was pretty good. I thought that the overall quality was clean. The proportions and anatomy checked out too. The environments (mostly the science room) looked good. No nature showcases or panoramics. Impact shots looked fine. Facial expressions were way too cute. Supporting details and extras also looked good and were nice additions that the manga didn't have.
Overall, the art quality was pretty good and there wasn't too much for me to complain about. The art was adapted well from the manga.
Animation: 7/10
Animation was pretty nice too. General motions looked fluid. Gestures and natural movements looked believable. Quick sequences looked good too. No selective framing, dropping frames, shortcuts, etc. Not really any impact sequences. Overall, I thought the animation was consistently above-average.
Characters: 7/10
Characters adapted well from the manga. I thought this show did a great job in giving life and personality to the characters from the manga, especially the main character, Ueno. The VA for Ueno really deserves praise for how well she did voicing Ueno.
Plot & Development: 6/10
Follows the manga pretty closely while taking some liberties in presentation to add punch or flair. Outside of the adaptation and just looking at the narrative itself, this story surprisingly has a lot of adult themes. It doesn't hold back any punches when it comes to deliberate service shots or lewd content, but the humor is very slapstick and cute. If there's one thing I like about this show is how cute the reactions of Ueno were. Overall, a fine adaptation. Not much else to say.
Music: 6/10
The bgm was fine, that particular hype theme did its job. The soundboard was also fine. No sound design to note. I liked some of the ED's.
Conclusion: 5/10
Adaptations of episodic stories turn out like this usually; not really introducing a lead-up to a conclusion and just ending the show as is. That's fine. There wasn't a dedicated conclusion really. The end of the show was just the end of the last particular skit that was adapted. One example of recent memory was Asobi Asobase.
Overall: 6/10
This was mostly just a personal taste sorta thing. I really liked how cute Ueno and her shenanigans were. I'm definitely going to pick up the manga again or watch an S2 if that's ever a thing. Overall, this adaptation was well done. I didn't personally find too much comedy in this, but it was hella cute.
