Probably pointless commenting on such an old chapter, but after having re-read this I find the persona's attitudes to be absolutely abhorrent.
Them not likely the problems and misrepresentations in the script is fine, but instead of getting together in an angry mob and confronting the script-writer and his friends is childish. Instead of trying to talk things out most of them insult the script and perform actions that just scream that they're trying to start a fight (e.g. the sorcerer guy dumping the script on the floor after stating what he dislikes, and the berserker girl pointing a potential weapon at the robot girl, then there is the dragon girl who begins leaving even before she states what she dislikes and only does so at the behest of another persona, the demon lord, chasing after her).
It could be argued that the personas can't speak to the script writer because he is a villager, but there were multiple personas there who were able to communicate with the MC, so they could've messenger-birded their complaints without the stupidity. It could also be argued that it's just how they are because their roles in this universe are literally a major part of their personalities, but that's like justifying a narcissist's actions by saying that's "just because they must have something underlying causing the narcissism", and based on the confronting personas' actions they are pretty much narcissists.
The writer could've easily made this much better by, as I stated before, using the MC as a messenger for the personas' complaints. This would've made the scene less frustrating, more teachable (not everything needs to be solved confrontationally and through gritted teeth), and far more natural as I'm sure not every high-schooler is stuck up and would be willing to talk things out first, especially over a play of all things.
Worse off if I remember correctly the next chapter or two won't rectify the personas' attitudes in any way other than to cater to their narcissism, but I haven't re-read them yet so idk and I don't want to fully spoil.
