I mean, she did create the bloody thing! 
Just watched it. 100 minutes of the young cast who were the main characters (Harry, Ron, Hermione, Malfoy, Neville Longbottom, The Weasley brothers, etc,) gushing over one another. Laughing and hugging and kissing, and reminiscing and brushing tears from their cheeks, as they whispered 'we're family... always have been, always will be.......'
Not ONE mention of the woman who created it all, and gave them the lives they have now. In fact many people were interviewed, including Ralph Fiennes, Helena Bonham Carter, Gary Oldman, Robbie Coltrane, Bonnie wright, Alfred Enoch, Toby Jones, Mark Williams, Jason Isaacs, etc. Not ONE of them mentioned JK Rowling.
All we got featuring JK, was two 10 to 15 second clips of footage from an interview she did 3 years ago. The narrator mentioned her ONCE! That's it! None of the 'stars' mentioned her, or thanked her for ANYthing. As I said, Harry Potter exists because of HER. Yet she was not deemed worthy of a mention or a thank you.
AIBU to think it's sad and also bloody infuriating, that she has been blanked in this manner? IMO, it's clearly because of the accusations of her being 'transphobic,' (which I don't think she is frankly,) and I am dismayed and somewhat disgusted, that these young people whose careers exist because of JK Rowling, are now treating her like a pariah.
I am a huge fan of Harry Potter, both the books and the films, and this has sullied it all for me now.
