Meet the Suzumiyas/YMMV

• Complete Monster: Oruki has been interpreted as this by some readers.
• Deus Ex Machina: See Freudian Excuse.
• Expy: Shino, one of the characters from the Omake explaining how Oruki and Naru met, bears multiple similarities to |Youhei Sunohara.
• Hype Backlash: Due to being one of most popular Haruhi Suzumiya fanfictions around (though, this is largely due to the author specifically going out of his way to request reviews), it has gained some significant criticisms from those who feel that this praise is underserved. This is mostly on account of the playing up of Kyon's status as the Butt Monkey, and Haruhi's Tsundere behaviors. To say nothing of Oruki or the author's history trolling FF.net (such as making a sock-puppet account to pretend to plagiarize his own work, which he then reviewed as himself and complained about when it didn't get the attention he wanted).
• Moral Event Horizon: For many readers, Oruki's No-Holds-Barred Beatdown of Kyon counted as this, making an already rather unlikeable character into a really unlikeable character. Whether what happens later partially redeems him is debatable, and let's leave it at that.
