I'm going to take this from another angle here.
The yehuborim are being blasphemous, yes. And very disrespectful towards our Gods. But this is actually coming back and biting them in the ass, hard — in a lot of situations.
I was also one of the teenagers that had exposure to such movies. It didn't make me hate the Gods. It made me curious.
Why are They portrayed like this? Who are They? Because I never really heard about any demons at church, or in religious studies. So such media served as my first exposure and made me curious about Them.
Then I discovered the official religious bullshit online, and I ended up digging enough to get to ToZ.
Does it justify or excuse what the yehuborim are doing? Not at all.
But people are much less willing to swallow the narrative they're painting, even in movies, and it does fortunately lead to people digging further into it and trying to learn more about our Gods.
Personally, whenever I engage in discussions with friends or social circles about the genre, I almost make sure to bring some light to the subject and redirect the negativity regarding our Gods to a more positive light.
