I don’t see any problem with the trailer. I don’t see a lot of negative opinions about it on social media, so it’s probably targeted for you to see it. There are a lot of edits about the trailer. There might be 1 or 2 things to say about the reboot but to hate the series just for a trailer doesn’t seem very intelligent.
‘Pretty sure you would remove a lot of these negative opinions if you exclude JK Rowling haters, books’ fanatics, original movies fans and racists who only have for argument that Snape shouldn’t be black. I saw someone saying they went woke just because of Hermione being Portuguese. I don’t think she’s shining in the trailer, but most people are biased because she’s replacing Emma Watson and everybody loved Emma Watson, but years later when she went pretty, people were making fun of her when we were kids.
Don’t compare with the movies or nostalgia will just fuck you up during your whole watch. Watch it as a separate thing. If Harry Potter movies released today, you would probably see all these negative comments because that’s how social medias work.
