Because a story can be re-imagined for a different medium and enjoyed by people? Who may in turn check out the original story and enjoy that, as well?

Others are just as entitled to enjoy an adaptation as you are to not enjoy it.

Some people enjoy seeing how a writer, director, cinematographer, cast, set and costume designers, etc present a written work.

Lots of people watch an adaptation and find bits they enjoy and bits they don't.

If you go through life only demanding or expecting experiences you will enjoy, you're going to be sorely disappointed.

I ended up reading The Expanse series because I loved the pilot TV episode so much. I've never read Foundation and I think I likely will in the near future.

> With these adaptations, the two options are "That sucks!" and "That's not Foundation!"

Others are entitled to opinions other than your own...
