Harry Potter was a smash hit about a boy discovering he’s a wizard and going to school in a magical world full of wonder and adventure. Twilight didn’t hit quite that high a note, but the story of a teenage girl who learns her classmate is a vampire and falls in love with him did quite well. The Hunger Games popularized the dystopian genre with a bow wielding teenager stepping up to survive death games, have angsty romances, and fight the power.
As far as I can tell, nothing has quite hit that same kind of high since and it may be awhile until the next truly big wave. But if it were up to you, what would the next big thing be about?
I would argue that an ending is an ending, an epilogue is an epilogue…it’s just a few pages to show all was well and that’s that. The true ending to the series is magical, in Harry’s sacrifice. I read a lot of next gen fic.
Cursed child is a whole different story and an insult. I am a huge theatre fan and was very disappointed by the cursed child script for sure - I might still give it live a chance but probably not. But yes. It was awful.
