According to an individual with knowledge of the situation, Amazon execs were concerned that Gero's take on the series would not have broad appeal beyond the franchise's already dedicated fanbase.
This is utterly insane. "We canceled it because it appealed to its dedicated fanbase" is just....I don't even have a word. It wasn't even that long ago when executives would have killed to have an IP that came with its own built in dedicated fanbase. That was a large part of why Disney even bought Lucasfilm, ffs. But no, modern executives can't help believing in the mythical "modern audience" that never shows up for any of the woke slop they churn out.
This makes me fear for Henry Cavill's Warhammer 40k show.
