The first reviews of the new ‘Harry Potter’ play are bloody ecstatic

It's the hottest ticket in London right now - and devoted fans last night became the first members of the public, anywhere in the world, to see Harry Potter And The Cursed Child on stage.

The show is now undergoing its previews (and will officially open on July 30) - and the first reviews are out of this (Muggle) world. Producers shared this tantalising image of the set to whet appetites before the show began: https://www.instagram.com/p/BGXQYqnNdnO/   But it looks as though appetites were well and truly whet long before that image was released. https://twitter.com/TimeOutLondon/status/740236865173901313 As for the audience's response, well, they were not disappointed. https://twitter.com/sueeves/status/740269761716719617 https://twitter.com/BazBam/status/740292923821072384 https://twitter.com/lizo_mzimba/status/740308265733607425 https://twitter.com/_tylerjohn/status/740270750494429186 https://twitter.com/eleanorbate/status/740300611011350528 There were reports of an owl going rogue - a first preview night kink that will be ironed out in time for when the show officially opens. https://twitter.com/JoshGrisetti/status/740271554030772224 Writing in her five-star review in 'The Mirror', Clare Fitzsimons says: "J.K. Rowling has made sure the audience will be back for part two with a cliffhanger ending to the first part. And if the second is anywhere near as good as the first there can be no other verdict. The child may be cursed but this show most definitely isn’t." https://twitter.com/HPPlayLDN/status/737525040262963200 Meanwhile, 'The New York Times' reported: "The three main characters remained true to their younger selves... The audience cannot be more thrilled or more appreciative or more ready to be caught up in the spirit of the undertaking." https://twitter.com/HPPlayLDN/status/737887188059324416 The play's storyline of the play is by Harry Potter author J.K Rowling, John Tiffany and Jack Thorne. For her part,  Rowling has asked everyone who sees the show to avoid spilling spoilers... https://twitter.com/jk_rowling/status/739736177943687168 https://twitter.com/jk_rowling/status/740445565826281472 ...and she isn't afraid to call out those who don't play fair. https://twitter.com/jk_rowling/status/740462043510243328 Harry Potter And The Cursed Child is at London's Palace Theatre.
