Ewoks … They are absolutely ridiculous and only exist to appeal kids and to sell toys.
Wrong. It’s an urban legend. Absolutely nothing to do with kids and toys.
They only exist because Chewbacca got a main role, therefore they could not be Wookies anymore, as they were in early drafts.
Since it is impossible to replace Ewoks with Wookies, getting rid of Ewoks is getting rid of Star Wars, as they were always part of it, from the very first draft.
