* AlternateCharacterInterpretation: The live action adaptation makes it seem more like Kindaichi is ObliviousToLove (at least in Miyuki's case) rather than just playing coy.
* IdiotPlot: ''Smoke and Mirrors'' featured a murder case that would have been solved incredibly quickly in real life, due to the extreme stupidity of the murderer's way of handling it. To elaborate: [[spoiler: The murderer killed a student and hid her body in a wall. Then, he started spreading a ghost story about a student that got murdered in the room where the wall was, so that the students would avoid it. Thing is, if a story about a murdered student starts spreading at the same time as a student goes missing, obviously people will start wondering and subsequently see a connection!]]
** This is also acknowledge in the story itself, when Kindaichi notes that [[spoiler:had the culprit simply reported the bodies, he would have gotten a light sentence and been able to live the rest of his life without guilt. Instead, he ended up killing two other students and attempting to murder Miyuki just to cover everything up, and ensured he'd be in prison for life.]]
* MagnificentBastard: The Moriarty-esque recurring villain that matches wits with Kindaichi.
* NightmareFuel: Most cases with a supposedly "supernatural" culprit count. There are many of them. The live action "The Seven Mysteries of the School" ("Smoke and Mirrors" in the U.S. manga translation) case had a scene involving a science lab at night with a jar containing a human head that suddenly...''opened its eyes''.
