It always kind of bores me when people complain, as it is so popular to do, about the abundance of remakes and reboots and sequels in movie theaters and on television. Because, you know, the forces behind the movies and tv shows are very nasty capitalists and make their decisions for anything but artistic reasons, let's take that for granted, but at the same time there is nothing either new or intrinsically capitalist about redoing and reworking and reinterpreting works of art. It's just something we do; one word for it is "dialogue."* Complain all you want about the remakes and reboots and sequels not being any good, and I'll agree with you about most (but not all) of them, but then you can say that about just about any movie or tv show or anything, really, so it's not particularly valuable as a critique if you ask me. Complain about how there's more of them now than there used to be and, well, maybe you're right, I haven't done a statistical survey, but on the other hand, try searching IMDB for "Wizard of Oz" and count up the results that come up from before the Judy Garland version, for example.
*Not that "it's always been that way" is a valid defense of anything (see below), but for one thing I wouldn't want art to stop responding to other art, and for another thing the supposed newness of the phenomenon is usually part of the complaint, as in, "today's creative bankruptcy..." etc.
But there's a different issue about the contemporary crop that I've been thinking about recently, and that's the convenient way that it allows for a continuity of white male supremacy in our popular culture. You know, if you're casting a brand-new show about people in space, or even a bridge crew for a new addition to the Star Trek franchise, the wacky kids these days might expect you to throw in non-white, non-male characters in decent proportions. But if you're rebooting KirkandSpock, there will be little objection to there only being two nonwhite characters and only one woman (or to these three tokens being spread miserly across two relatively minor characters), because that's the way it's always been. Not only that, but people will get upset if you try to change anything, because Spock's white! It's canon! I mean, me, I think Spock has been and always shall be Leonard Nimoy, but if you're going to throw an ill-fitting Halloween costume on Zachary Quinto and call it Spock with a straight face, I see no reason why the race and gender of these characters must be eternally fixed. Or my god, you should see, if you haven't, the outrage any time it's suggested that The Doctor could regenerate into something other than a white man, as if race and gender were discrete, unalterable genetic categories for an alien whose entire physical body changes and comes back to life every time he dies. For an even more instructive experience, try googling Idris Elba Thor.
