November 8, 2026 · 22 min

Show notes

Harry Potter on HBO is now 7 WEEKS away from premiering, and they just recently revealed that the first episode will be TWO hours long.


So there’s a lot of buzz about the show at the moment.


I was also perusing the Harry Potter on HBO subreddit today and I came across a thread discussing ‘plot holes’ that people want addressed in the series. And since I recently made a pretty lengthy plot hole series, I thought I’d take a look at some of them and give my thoughts.


Let’s check it out.
