Jeremy Vine calls Black Panther cast "overwhelmingly black"

He was a bit crude and simplistic about it sure, but I don't think it's silly to highlight it. It's obviously notable that Black Panther has a predominantly black cast, as it's something that hasn't happened in a superhero film before. Pretty much every superhero film has been a mostly white cast. In fact, as far as I'm aware, the Blade trilogy are the only other superhero films in which the main lead is black, though I may have missed an obscure one.

Luke Cage was before Blade and this.

As far as I know there's never been a Luke Cage film. If you mean the TV series, then it definitely wasn't before Blade.

And sure, the Luke Cage TV series is part of the same genre, but still, it's not a feature film.

Calm your tits.

I was saying that in recent years there has been a move towards black superheroes which, in recent years, started with Luke Cage. Cage in the comics came about before Blade, but Panther is older than both. The weird thing is that it is not only the superheroes which are black but the entire format: the other characters, the cultural references. Egregious pandering to the black community, which is awkward because you know it's contrived.

I don't see why Black Panther's conscious largely African cultural context is fundamentally any different to Thor's largely Norse-Germanic one or Wonder Woman's largely Greco-Roman one. They're sci-fi/fantasy worlds inspired by particular real world cultures.

Depends what you mean by "contrived". If you mean that productions like Luke Cage or Black Panther probably required more conscious attention to the cultural references and details than an equivalent "white" production, that's probably true. That's always going to be the case when whites are the dominant majority in the West and the "white" perspective tends to be assumed as the norm.

Let's be clear; they're legends and not real-world cultures. The difference is that Thor and Wonder Woman are legends which by coincidence involve white figures. They were not chosen simply because of white faces.

Luke Cage is set in real America, which is not abstract, and in fact there is a mix of white and black people there (even in Harlem). The cross-section of society Luke Cage exists in is not in reality all black; only abstractly all black. The creators went out of their way to defy logic and make it an all-black-environment for the sake of making it black.

But note in the legend of Thor, which is supposedly all-white, Idris Elba made an appearance. Where is Panther/Cage's Idris Elba?

Not that I even have a problem with focusing on a particular culture, though I don't appreciate division and I think by making a product solely for X cross-section of society that perpetuates division. My issue is that the product is black, it is meant to be black, and it is rather odd that it is all black since it purports to be in a real-world environment rather than in legend.

It doesn't purport to be in a real-world environment, it is set around a country that kept its entire existence a secret. Everyone thinks its a bog standard central african country whereas its secretly the most technologically powerful nation on the MCUs earth that has a nationwide cloaking device that no outside aside from Serkis' character has ever seen (and now Cap and Winter Soldier). That's the equivalent of Egypt have the technology from Stargate and no one knowing.
