First of all I had no idea this existed until I saw an ad for it after the first episode had already aired which should've been a hint on it's own. I love everything to do with the Wizarding World Of Harry Potter and I have read the books and watched the films countless times so the idea of a gameshow was very exciting to me. But I couldn't have been more wrong in thinking that!
Everything about this show is cringeworthy, there is nothing unique about how it plays out it's just a hodgepodge of famous gameshows mashed together. This would be fine is it was done well but its executed so poorly and it seems like Hellen Mirren doesnt even want to be there. She plays the role of the game's host and she cuts the contestants answers short more times than I could count including when they were "introducing themselves and why they love Harry Potter". The "contestants" on this show are terrible actors and they are clearly ready from a script and it's not well hidden at all. There are a few segments with "celebrity fans" of the series as well and you can tell they were pre-recorded but they try to edit them into the show as if the celebrities are talking to the contestants live and you can tell this isn't the case. As for the questions...some of them are so ridiculous like asking which couch Hermione's parents owned and having the contestants pick it out from 3 couches.
All in all if you are a true fan of the series I feel like you will be extremely disappointed in this show and you shouldn't watch it. I don't know what they were going for but it really is awful and the production feels so rushed.
