It is difficult to list everything this show did wrong without giving spoilers, so this will be short.
The story is introduced with Mishiro, a manager who was displeased with the course things in the company were taking, so she proposed some huge changes. This changes lead to a series of individual episodes that tried to develop some characters.
But instead of development, they grew in annoyance or stayed the same, leaving their appearance as the only good thing about them (yeah at least they are waifu material, though not all of them). The drama was poorly executed, extremely forced with embarrassing dialogues, and it is not
an exaggeration to say that the dialogues were almost at a Mexican soap-opera level of foolishness and melodrama.
Towards the final it started to show some signs that AT LEAST it was going to have a decent final but it finished just as dull as it started
The only merits I can find: The animation that tried to build an atmosphere that could have been interesting without all the flaws I mentioned above and the background music that was sometimes actually good but went to waste combined with the shitty dialogue.
To conclude, in the end this season leaves the spectator with an “absolutely nothing happened here” feeling and questioning “that’s all there is to Im@s CG??”
