Vernon Dursley's Political Opinions
The new Harry Potter TV series should ignore J.K. Rowling's decision to have Harry's Uncle Vernon express political opinions, especially regarding the UK Brexit referendum. This unnecessary addition doesn't align with the original storyline and has no relevance to the 1990s setting of the series.

Wizards Didn't Used To Use Toilets
