These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: Holy God, the fights between Sharona fans and Natalie fans.
Crazy Awesome: "It's a gift... and a curse." In "Mr. Monk and the Red Herring", Monk goes to a museum and sees the body of a caveman that supposedly froze to death. Monk determines that he was actually murdered and actually figured out what happened. We never actually get to hear it, but suffice it to say Monk is a really good detective to solve a 30,000 year old murder.
Dude, Not Funny!: Some viewers' reactions to the show's humor and treatment of mentally ill people.
The reaction that some OCD sufferers and their loved ones have to the show.
Family-Unfriendly Aesop: In the subplot for the episode "Mr. Monk Is Stuck In Traffic," Monk reports a trucker for driving crazily on the road, it wasn't the first time the trucker in question did so, and they fired her. She then, during the traffic jam, decides she wants to kill Monk as revenge for getting her fired (and her brandishing a crowbar implies that she is not bluffing), and in order for Monk to evade a potential beating on his part when found by her, he is forced by her to withdraw the complaint by claiming he lied about her speeding as revenge for her turning him down in the hand of marriage. Basically, the moral is that, unless you want to be beaten down and possibly killed by the person you reported, don't squeal, even if the person being squealed on deserved the punishment.
Throughout the series, anytime Monk gets up the nerve to try to fix his OCD issues and succeeds he always loses his brilliant detective skills as a consequence and always ends up having to undo it to get them back. The message seems to be "The ability to do your job is more important than fixing a crippling problem that ruins your life."
Some of the trivia questions on Treasure Chest in "Mr. Monk and the Game Show" count. For example, Monk's question at the Bonus Round is, "Who was the first president to win a Nobel Peace Prize?" The answer, if Monk had not been trying to nail Roddy Lankman for a cheating scandal, would have been Theodore Roosevelt.
In "Mr. Monk and the Birds and the Bees," there are several sports jerseys on the walls in Rob Sherman's living room. These includes a #21 San Antonio Spurs jersey that was that of Tim Duncan, and there is a #3 Denver Nuggets jersey that is that of Allen Iverson. Both Iverson and Duncan were League MVPs. The presence of these jerseys implies that Sherman may or may not have been their agent.
Hilarious in Hindsight: In the novel Mr. Monk Is Miserable, published in early December 2008, Monk finds a skull in the Paris catacombs belonging to a recently deceased man. The skull is identified by dental records as Nathan Chalmers, a man who committed a pyramid scheme in America, and who faked his death to avoid prosecution. Barely a week after the book was released in hardback, Bernard Madoff was exposed and arrested for one of the largest Ponzi schemes in recent history. Madoff was identical to the descriptions of Nathan Chalmers: the architect of a massive pyramid scheme whose victims included several of California's wealthiest and most sophisticated persons.
In Mr. Monk Is Cleaned Out, Lee Goldberg has Fun With Palindromes in Bob Sebes, an Expy of the original Bernard Madoff.
In the episode "Mr. Monk Goes Home Again" Leo Howard played a karate kid.
Idiot Plot: "Mr. Monk and the Foreign Man" relies on everyone being a complete idiot, even for the character development Monk gets. The crime in question goes like this: restaurant owner Kenneth Nichols drunk dials a friend of his who happens to be on vacation while he's driving. However, said friend left his cell phone at home, so the housekeeper answered. Nichols runs over a visiting Nigerian woman while he's talking, so he then proceeds to drive over to the friend's house and kill the housekeeper to cover up evidence of vehicular manslaughter. Where it becomes an idiot plot is this:
The fact that Nichols runs over a woman in his delivery van, that has the name of his business "Le Poisson Bleu" on it in great big letters at 8:15 PM, while recklessly driving down a busy street (and under the influence of alcohol) and he thinks nobody is going to notice. More so, he thinks the broken headlight is going to be the dead giveaway, as opposed to, say, the words "La Poisson Bleu" written in big ass letters so conspicuous that even a stoned slacker sees them.
That says nothing of the unseen Sergeant Kramer who was in charge of the hit and run investigation and failed to find that the tire tracks were made by a van or the shattered headlight glass left in the street, or failed to realize that there was a gas station nearby with potential witnesses and security cameras.
Plus the fact that Ansara Waingaya steps into the crosswalk the moment the cross street's light turns red, when common sense dictates that you should look both ways before crossing to make sure that traffic on the cross street actually stops, or at the very least, notices you.
Jerkass Woobie: Monk, who treats his friends callously without actually realizing it. Usually the source of an Aesop Amnesia when he learns to appreciate and treat them, especially Natalie, better, which he then promptly forgets next episode.
They Wasted a Perfectly Good Plot: Stottlemeyer finds out his new girlfriend is also named Trudy, he seems defensive about letting people know this (especially Monk). A few episodes later he is talking to Monk about it as if they have already talked about this off-screen.
The Woobie: Monk's cringing and general pitifulness when being confronted with one of his phobias generate an instant oh-the-poor-thing factor and tend to put one in mind of a small child or bewildered dog; on top of that, cruel minor characters unacquainted with Monk are always around to mock him, stare at him, or try to forcibly make him "get over" his fears. It's almost painful to watch, even when played for laughs as it usually is. (For some reason, neither Monk nor Natalie/Sharona ever bother to explain Monk's OCD, instead describing him as being "particular" or something similarly vague; thus, the other characters are rarely sympathetic to or accommodating of his problems.)
Could be justified. If they "did" explain, people might react to Monk the way they often do to other, more visible, disabilities, such as treating Monk as if he is an anomaly or is helpless. Or maybe it's just because his particular manifestation of OCD would take too long to explain.
