The five star reviews are rolling in for Harry Potter and The Cursed Child, currently showing at the West End's Palace Theatre in London.
After weeks of previews and sworn secrecy – although there were leaked reports of a feral owl – the critics have finally cast their verdict and pronounced the play a smash hit and a triumph for British theatre.
Written by Jack Thorne, Harry Potter and The Cursed Child is set 19 years after JK Rowling's seventh book Harry Potter and The Deathly Hallows.
The play's action revolves around the three wizard stars who are now in their 30s with their own children, off to Hogwarts.
Lasting a total of five hours and split into two parts, Harry Potter and The Cursed Child is a theatrical marathon but complete magic for both seasoned, and not-so-seasoned, Potterheads.
And while it looks like Hogwarts will be a fixture in the West End for some time, America can have its Hamilton, while we've got Harry.
