I want to open by saying that I do not dislike this show, but it isn't very good, and when I say it isn't very good, I don't mean in a "this turd sandwich isn't very good" kind of way, I mean in the way movie theater popcorn isn't very good. It is not very exciting, or creative, or well characterized. but it's good for a chuckle or two and passes half an hour inoffensively. And that is, seemingly, all it wants to be, in which case, mission accomplished. But it'll join a whole host of barely-descript shows in the dustbin of anime history.
The animation isn't great, serviceable, but bland and stiff. The music is odd, with lots of nods to more famous music but in downgraded form. The OP and ED are pretty rough, the ED in particular which is astonishingly bad. I don't get the hate for the hololive Vtubers who performed it though, it's the production and composition that suck, not the singing, per se.
Anyway, for a shounen CGDCT show it's not terrible, but way behind something like Gabriel Dropout, for example. The term "paint by numbers" applies, but it's not the worst example of that.
