if I may be brave enough to say, the reason we don't get accurate representation on krishnarjun dynamic is simply the fact the society won't accept the nature of it especially between a "god" and a "mortal" and ESPECIALLY between two (married) men.
Platonic or romantic the society would shun away any possibility also for such a deep connection to imply something more than friendship and no showmaker would want that
So god/devotee becomes the easiest dynamic to show the deep connection without the audience having to have any deep thoughts about them two
It's less about the god/mortal part because Madhurya Bhakti exists and I haven't really seen anyone even imply that tbh.
1. Homophobia/internalized homophobia and that queerness should "stay out of religious texts/not everything has to be queer and woke" etc.
2. "They're just best friends/brothers" mentality/general headcanon but that is simply the cherry-picked version of them. But I have already shown that if Krishna said the things he says to/about Arjun to someone he considers platonic, say Draupadi, or even Sudama, it would sound weird as fuck.
3. Most people expect Krishna to only love his female love interests, like Radha, Rukmini, Satyabhama, etc., because most people either identify with/relate to the female love interest (usually female devotees/stans/madhurya bhakts) or with Krishna having said female love interest (usually male devotees/stans).
4. The only male lover some of them are willing to accept is Gadadhar, but that is again because he's literally the male version of Radha.
5. They are "NarNarayan" and hence brothers so they cannot be together. Ig that's the only strong argument. However, many ppl using this argument usually ship Subhadra and Arjun, who are maternal cousins. So...
At the end, especially in times like this, where queer rights are already at almost their lowest in India, we will probably never see a KrishnArjun adaptation that implies a kind of tension that's just more than platonic, or truly capture their obsession with each other. Or even make Krishna even dare say canon monologues like "I cannot live on this earth without Arjuna" or "My family, my wives, none are as dear to me as Arjuna is".
Unless grassroots filmmakers really wanna take a risk and do this, we'll never have such an adaptation that truly incapsulates canon KrishnArjuna. Because the canon itself is something that they don't wanna admit.
