If blame game happens - then it shall be the currently ignored Raman becoming the one with more disappointing actions
I don't think Ishita is disappointing exactly - I think she's making a mistake despite her intentions and that makes her imperfect. Instead of trying to justify and portray her as perfect, it should be celebrated that she messed up like a real person, like Raman, and like every other character. They are disappointing in the sense of the horrible portrayal and treatment of a father's emotions & her overly passive behavior is out of character but taken in isolation - Ishita is flawed & messed up here and there is no other way about it
