- Quick Answer: Book fans are praising the HBO trailer because the TV format’s extended runtime allows for a more faithful adaptation than the original two-hour movie versions.
With the release of the first trailer for HBO's Harry Potter TV series, fans are now weighing in on the early look, including long-time fans of the best-selling novels.
To this day, there have been debates about why the TV series adaptation needs to be made, considering that the movie adaptations have become classics and are revered by fans to this day. However, some have argued that the TV series version could also provide an opportunity for them to adapt the novels to a longer runtime.
Why Harry Potter Book Fans Are Praising the HBO Series Trailer
The reactions to the first trailer of the Harry Potter TV series have been polarizing, as the debate surrounding the necessity of the new adaptation continues to dominate the discourse.
However, some fans online have also noticed through the trailer that the TV series adaptation will be an opportunity for them to be faithful to the source material, given that there are eight episodes (or hours) of runtime.
While millions of fans and audiences have revered the movie adaptations, they have also been criticized by book fans for making changes or cutting some scenes, as they can only cover the entire story for 2 to 2 and a half hours.
As one of the YouTube comments said, "It’s like reading the book in a different font."
The sentiments are similar on social media. While many fans are conflicted about whether to support the series due to J.K. Rowling's controversies, some have also noticed that it appears to be more faithful to the books.
It would be interesting to see what the reception for the series will be once it premieres on HBO and HBO Max, and whether it is indeed going to be more faithful to the books than what the movies did.
