That's a really odd thing to point out, as even the earliest written records of the Odyssey are later interpretations of what was a story passed in oral tradition. And on top that, what most of us have read, have further passed through one ore more translations. Each of the transcriptions add interpretation, especially ones that move from ancient languages to modern.

Maybe it's the modern era with brands and so many off-the-shelf prepackaged products that there is an invisibly applied assumption that there is only one true form of a product or piece of literature. That's coming from a consumerist, marketed, branded culture. Looking with a longer perspective, most archetypal stories and myths are interesting precisely with interpretation of their time making them relevant and connectable again in the time of their retelling.
