It feels like there are no epic novels like Harry Potter these days

I think it's more of a subject matter issue rather than a lack of creativity.
Even with Harry Potter, the subject matter was quite cliché,
but it became a hit because of the writing talent and the storytelling.
It's a bit disappointing.
Whether it's fantasy or general fiction, we need more epic works
to have more things to enjoy...
Since HBO is making a 10-year Harry Potter series covering all the books,
I guess I'll just have to rewatch those.
