Mummenschanz. Ein Roman von der bizarren Scheibenwelt.

The reviews highlight the book as a laugh-out-loud funny and highly entertaining installment in the Discworld series, particularly praised for its focus on Granny Weatherwax and Nanny Ogg. Readers found immense joy in the witches' antics, their journey to Ankh-Morpork, and their unique brand of "headology" as they navigate the world of opera. The novel is celebrated for its sharp wit, smart observations, and well-crafted humor, frequently eliciting sniggers and full-blown laughter. Many consider it an excellent parody of the classic "Phantom of the Opera," with some even finding it more enjoyable than the original inspiration. The introduction of Agnes Nitt as a new character is also well-received, with her nuanced portrayal and common-sense perspective adding depth to the narrative. Beyond the surface story, the book is lauded for its satirical commentary on art, jealousy, greed, and the peculiarities of opera, all woven into a compelling, lower-stakes murder mystery that many found refreshing.

However, some reviewers expressed reservations, suggesting that Pratchett's parodies of existing works can sometimes feel less robust than his original Discworld creations. A common point of critique is the perceived lack of deeper, "meta-topic" plotlines - such as politics, economics, or timeless societal issues - that are often central to other Discworld novels, leading to a less complex reading experience. For some, the inherent ridiculousness of opera itself left less room for Pratchett's satirical genius to truly soar. Concerns were also raised that the witches, usually tackling broader social commentary, are confined to a more personal crime thriller, which some felt didn't allow them to reach their full potential. Additionally, a few found the ending rushed or confusing, and for readers unfamiliar with or uninterested in "The Phantom of the Opera," the parody aspect diminished their overall enjoyment. There's also a sentiment that this book, as a parody, might not be the ideal entry point for new readers, potentially misrepresenting the full scope of Pratchett's work.

Despite these varied criticisms, the overall consensus remains largely positive, with many reviewers rating the book highly and calling it a delightful read. It is generally considered a strong entry for fans of the Witches sub-series, offering a charming and humorous adventure with beloved characters. Readers who appreciate Pratchett's distinctive wit, satirical observations, and character-driven comedy, especially those with an affinity for "The Phantom of the Opera" or an interest in opera, are likely to find this book immensely enjoyable. It offers a compelling mystery alongside its humor, making it a good choice for those seeking a lighter, smart, and funny story. While some suggest it might not be the definitive starting point for newcomers to Discworld, it comes highly recommended for established fans looking for another engaging romp with Granny Weatherwax and Nanny Ogg.
