For me the point of an adaptation is to recreate the source material in another form, and even if you don't do an exact recreation of the one of the source material's stories, at least capturing the tone and themes of them is a hugely important part of doing an adaptation If you aren't going to at least try to make the adaptation feel like the source material, then there's no point in doing an adaptation..
I couldn't disagree more. The point of an adaptation is to create something new, using the source material as the starting point. It's to take an existing concept and reinterpret it for a new audience or a new medium, to turn it into something it wasn't before so that it can appeal to new people. Fandom today is so infuriatingly selfish and possessive -- they think the only point of an adaptation is to appeal to fans of the original, which makes no sense, since they already
have the original. Adaptations are about inviting new people into the tent, not hoarding something strictly for the people who already like it.
There is no one "right" way to do an adaptation, any more than there's a single "right" way to do anything creative. Some adaptations succeed by being faithful, yes, but others succeed by turning the source material into something altogether different. The Bill Bixby
Incredible Hulk was as far removed from the source material as it was possible to get, but it was still one of the most beloved adaptations ever, because the new thing it created was worthwhile in its own right. The Moore
Battlestar Galactica was a deliberate and radical contrast to the style and tone of the rather silly original, and that was its value, even if it often went too far in the other direction.
Scooby-Doo: Mystery Incorporated was made specifically to appeal to people who weren't Scooby fans, to do a smarter, funnier deconstruction and a much darker, more serious horror saga at the same time. And yet it also managed to be true to the characters and an affectionate tribute to the very thing it was poking fun at and vastly improving on.
Ultimately, what matters about a work is how good it is in its own right, regardless of what its source material is. If you can make a story good by drawing on the source, then you do that. If you can make it good by departing from or contrasting against the source, then you do that. The value of the work
in and of itself is the highest priority. The source is just an ingredient in the recipe. It's always wrong to say "You should never do X" or "You should always to Y." Either X or Y can be done brilliantly or badly. It's the execution that matters, not the category.
