The first-ever promo of the Harry Potter series was unveiled last night, on March 25. And the internet is divided, as expected. While some lauded the new series’s detailing and compared it to JK Rowling’s book, others thought Daniel Radcliffe’s films were better. As the world continues to watch the promo, let’s take a look at fan reactions to the teaser.
Harry Potter Series promo: Fan reactions
On Tuesday night, Dominic McLaughlin appeared as Harry Potter in the first-ever promo of the series. Fans got a glimpse of the key cast, Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley.
Comments on Instagram reads: “This is beautiful yes OG is OG! But this is soooo nostalgic”, “Looks like a more detailed story this time and bro the music is [fire emoji]”, “THIS IS ABOUT TO CHANGE LIVES!!! Again!!!”, “Idk it’s still the original cast for me… I want to like the new one and hope I do, but it’s so hard with the OGs ingrained in my mind and heart”, “Im gonna have to watch but the originals are just too special”, “The problem with this show is that it is remaking such an iconic series. The original casting was so perfect. I’m not sure audiences will be able to separate the two or if they will be telling themselves every scene “that’s not Harry. That’s not Ron”, “I’m sure I’m not the only one who feels this. I feel happiness and kindness. We really miss that time, and we need it now. And it’s not just because we’ve grown up, but because the world has changed. People have changed. But Hogwarts hasn’t — it stayed the same. Wow.. it’s so perfect, all this details”, and others.
