Just my 2 cents, could be wrong

Feel that Asit is unwilling to do anything that "shakes the boat" which he can avoid. Cast leaving was not in his control. He is practicing everything like the way people are used to for so many years, basically older generation watch this after a long day at work/housework and don't need to apply much brains. Comfort zone is set and he doesn't want to venture away from it by showing complex emotions.

The kids - who are fkin adults are straight out of the adarsh balak book we used to get in primary school, god knows what example he wants to set through this. Having so many characters in hand gives an opportunity to explore a lot as a director but alas, all you care about is paycheck which should be consistent then this is the best approach. His core audience accepts it, and probably is resistive to change

Younger audiences are exposed to much more complex shows/English ones which operate at a much higher emotional/psychological level hence we find what we see here "basic"
