When we complain though, people often tell us companies don't owe us anything. But I would point out the reverse is true, when film makers or game producers make movies, shows or games we aren't interested in, they aren't owed our business. I make games on a very small scale and while I would love for my games to sell more, blaming the customers, rather than looking at what I can to do increase their interest, is the wrong way to go in my opinion. Sometimes people want what is tried and true in their games, and they don't necessarily want that advances the system (and sometimes they do want advances). Part of design and art is figuring out how to connect to your audience. I think D&D's issue in this respect is it is the biggest game. So they will always have to find a sweet spot that appeals to the largest cross section of the fandom (same with Star Wars). There are plenty of smaller game companies doing all kinds of creative and interesting things, because they are not working with that very large D&D base that has built in expectations (and by the same token, science fiction shows and movies that aren't tied to an existing property or fanbase are a lot more free to experiment and do things a bit differently)
