I'll be real, I think this is more of a problem with Fandom than Google. Fandom has been abusing the fuck out of their SEO lately, and manage to push their shitty site to the top results on almost any fiction media-related search you do now.
Yeah, Google's AI got the preview wrong, but it probably wouldn't have happened if Fandom wasn't constantly injecting themselves into every single search. They allow users to post anything they want, without any vetting, and then push those inaccurate posts to the search engines.
Half the time, the page on Fandom is a 100% copy/paste of the page from Wikipedia, except with a thousand ads littering the page. Guess which one shows up first in the search results, though?
