How do you feel about another person playing in the sandbox of a creator who may be dead?

Next month, those of us who like the Dune story of Arrakis and the Great Houses all backstabbing each other for thousands of years get a treat. It's called Dune: Prophecy and it is inspired by the novel Sisterhood of Dune which is co-written by Brian Herbert and Kevin J. Anderson. I actually didn't know this, and I only found out yesterday because there is so much hate for Brian Herbert online. I haven't read any of his books, but now I'm intrigued. Maybe I should finish up my Dune readings (as I only got to the end of God Emperor) and then moved on. But the kinds of vitriol that's targeting Herbert's son, Brian, basically goes along the lines of "I consider all of these works fan-fiction" or "I hate the way they are retconning characters. Some of the choices don't even make sense." For nerds who are deeply and emotionally invested in these science fiction works, these are real "clutch the pearls" statements. 

All of this makes me question what right anyone has to play in someone else's sandbox. Let's step back for a moment and think of other sandboxes that people are presently playing in or have played in within the last few decades. We've got Tolkien's Lord of the Rings, we've got Disney happily playing in the Star Wars sandbox and the Alien sandbox, and we also have Max which played in the Watchmen sandbox with a mini-series. Some people get upset when a character becomes black (when they were previously white). Others get upset when a character gets recast with a female (think way back to the Battlestar Galactica reboot and the SyFy channel's decision to make the character of "Starbuck" a woman when it was previously played by Dirk Benedict in the 1970's show).

In some cases (certainly) there are people who object to seeing something filmed that previously was just a mythical thing. The Clone Wars was like this. So, you had it name dropped by Luke Skywalker in A New Hope when he spoke to Ben and asked "You were in the Clone Wars?" And every single one of us wondered what the heck the "Clone Wars" even were, and so we made up things in the dearth of information that was available. So we imagined far off battles and struggles, and it was natural for every one of us to make it bigger than life in our imaginations. But when they showed up in film...even though there were lots of epic scenes...it could never live up to your dreams. And to some extent, we even get upset with original authors of material revisiting their sandboxes. The Matrix strikes me as one of these, calling any further attempts to explore the stories and themes of The Matrix a cash grab, as if audiences will just watch these things as brain-dead drones because they don't actually know what is good. "Oh it has Matrix in its name so I'll give it money." I don't think that's how any of this actually works.

Look, people will always try to recapture lightning in a bottle because it just feels so good. Jurassic Park was an amazing idea. I don't blame people for making that "cash grab" and trying to recreate the same wonder that we saw in that first film/book. It won't ever happen. Still...there's room to play in that sandbox. I for one think it would be cool to stop focusing on dinosaurs and cloning and set a world that is "post Jurassic Park" and do a spy thriller where it's a kind of Mission: Impossible scenario of world governments with the added part that dinosaurs are real and have been unleashed upon the world. I think that would be really cool...kinda like what happened when people thought of Alien and Predator and someone said...why don't we mash these together?

In the Star Wars universe, I've often felt that a series centered around a bounty hunter would be magnificent. Well, we got that in The Mandalorian and I was right. For what it's worth, I think the best Star Wars stories keep the Jedi and the Sith way in the background or not even mentioned at all, and they focus on the politics and danger present with a civil war that spans a galaxy. There's just so much you can do with that, and they haven't scratched the surface. For example, what about a series that has a crackpot team of rebels whose entire mission is to break into a skyscraper on some important core world where the tie fighter was developed to say...find the plans for something else...like a fuel depot or something like that? That would be a ton of fun.

Furthermore, I will never be so stuck in the mud that I won't think that a descendant of a famous author (like Brian Herbert is to Frank Herbert) doesn't have a right to play in the sandbox that the famous author created. I say, go for it. It seems silly that great ideas should just be done and finished when there might be more to tell in these enormous universes that were so meticulously created by a person who may have been bordering on obsession to get things completed before they kicked the bucket. I'm sure that long after George R.R. Martin is dead, we will have people playing in the Game of Thrones sandbox with stories about Arya and the other continents she discovers and on and on and on. Anyway, that's my opinion on this particular topic. So in finishing, I ask you all this question: do you like it when someone else plays in a famous property's sandbox? Or do you find this "fan fiction" offensive to your sensibilities and disrespectful to the creator?
