And deleting negative reviews by bigots at least would be more defensible than deleting negative reviews from fans of Tolkien who take issue with the treatment of the work they love.
EDIT: I still haven't seen the show yet and I originally thought the issue with review bombing was similar to people like me hating the show foundation on Apple TV... I see now that people claim that a lot of negative reviews were due to the race of characters and people claiming the "show is too woke". In that case, it's actually more of a similar situation to Lightyear. Still, it's very interesting to see the differing treatment of Lightyear, a pixar property compared to this, an Amazon show.
