This is the best seiyuu show yet, but I totally understand why nobody seems to be interested, it looks cheap, the title sounds boring, the premise of the show described in the summary doesn't seem to lead anywhere, and I only watched it because I was emotionally really upset by a certain episode of Gundam GQuuuuuux. It does have average animation with a flat look, that part is true, but it has a great story that really isn't in any way summarized by the summary, so let me have a go at it:

Yumiko and Chika are high school classmates pursuing a voice acting career as friends and rivals. Just as things are starting to look good with their own web radio show is being rolled out, turmoil strikes as their real world identities have been leaked online. Yumiko realizes amongst the chaos that she is not nearly as talented as her rival, meanwhile Chika is deeply troubled by a scandal and internet bullying. This is the story of how these two young professionals overcome these challenges to their career, personal life, and relationship with each other, in pursuit of a career of their dreams. The show for some reason really want to pretend it has this gimmick that the two leads hate each other, they don't, in fact I'm upset this isn't Yuri show, it really should be a Yuri show, I would die for that. They're rival-friends really, and that makes it very interesting when one of them has a problem, should the other help or should they not help? As a friend probably yes, as a rival probably no, as a college randomly offering help has unwanted implications.

Many seiyuu shows have this fantasy rainbow unicorn land things going on where where everyone is super nice super helpful super ideal. This show probably goes the furthest (other than Oshi no Ko and Perfect Blue) in having some actually bad actors that add some genuine distress to the characters.

Being a seiyuu show it of course has voice acting scenes and they're the best yet. Here in the final arc of the story when they're acting for this show-within-show we actually just get the pre-vis frames which is realistic but other seiyuu shows often have at least some of these scenes be imaginary completed shots. The choice here to stick with pre-vis with no music, no sound effect is straight forward but genius, because it super highlights the voice acting and voice acting alone. This show-within-show not only is quite long, it also is an exciting mech battle sequence that parallel what happens in the 1st level show, reflecting what the characters might be thinking at this point in the story. The voice work by the real-life actors are also amazing for this part and I really felt the growth in acting skill for the 1st level show characters which is legitimately hard because again there's no music no sound effect no animation. Bonus point for "final battle" Very much enjoyed the show, hope it gets more seasons but that seems unlikely.
