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.
Angst? What Angst?: So you have experienced this massive explosion, your friends and colleagues are injured, some seriously, a woman died, you know that it wasn't an accident and all of your personal belongings are destroyed. A devastating and difficult to move on from event, right? Hardly; everyone just picked up, began rooming with one another and went on with their lives within an episode or two, well except for Peter,Kimberly and Alison.
Brooke in her final episode, who we are supposed to feel sorry for, but due to her actions over the season and the hilarious "scrunchy face" she gave that was supposed to show that she's upset and about to cry, it came off as this.
As powerful(and heartbreaking) as Sydney's death was, Craig's reaction comes off as this. Interestingly enough, the actor doing the Spanish dub of that scene provided more raw and genuine emotion in his portrayal over the original English acting scene.
Nightmare Fuel: Kimberly's removal of her wig and the revelation of a huge, disfiguring surgical scar on her head from brain surgery. In Melrose Place's E! True Hollywood Story, Marcia Cross admitted that fans would tug at her hair to see if it were fake.
Then there's also Brooke's pale ghost coming back to seduce/taunt Billy, which caused him to (temporarily) turn into a Jerk Ass.
In a Shout-Out to Silence of the Lambs, Michael is visiting Kimberly in jail after she blew up the complex, and she breaking through a glass door just to repeatedly stab him to death. (Un?)fortunately, it was All Just a Dream.
In the episode where Sydney accidentally joined a cult and she tried to leave, she is then overpowered by some other members and thrown into a locked cage built into the ground, all while screaming at the top of her lungs to be let out.
Peter in the mental institution, particularly when he is about to be given ECT and he keeps insisting that he is a medical doctor and not a mental patient and tries to prove it by yelling out medical terms in a desperate last-ditch effort to stop the treatments, which occur anyway.
How about Richard's arm popping out of his freshly dirt-filled grave and struggling to claw at some sturdy land above it? It's made even worse by the creepy, sinister music playing while this is happening.
Peter and Amanda being with anyone other than the other one is regarded as this.
The Scrappy: Brooke is arguably the first person that comes to mind. She was so unpopular with fans, the producers had to kill her off just to appease them due to the level of hatred her character received.
Taylor is another contender. Many fans even blame her introduction for reason behind the show Jumping the Shark.
Samantha is considered this among the fandom as well, due to both her and her worthless, ex-con deadbeat father (the best example of the MALE scrappy of MP) running down Sydney at her wedding AND that fans considered her too bland and a far more boring wife for Billy.
Strangled by the Red String: Plenty of occasions, but Jake and Alison was the best example. The two of them were friends for the past four years when, out of nowhere, they fell in love, Alison became pregnant, they were married and Alison was forced to terminate the pregnancy due to medical reasons. A season later, they were split up, Alison left L.A. and Jake decided to go live with his ex-girlfriend and their son.
Wangst: Dear Lord, Craig in season 6. On one hand, it was understandable (becoming a sudden widower, especially in such a violent way, does do that to a person), but on the other hand, the writers took it Up to Eleven and let him wallow in misery throughout the season, culminating in him being Driven to Suicide in the season's penultimate episode.
What an Idiot: The general fan reaction towards Michael after he forgave Kimberly for running him over, especially after she sent him to jail later in the season. Even worse, when he told Kimberly he knew it was her all along, what is his "punishment" for her? They began making love.
What The Hell Costuming Department: Jane's supershort, lopsided "pixie" cut throughout much of season four was universally hated/mocked by the fandom, with many believing she had it cut by a lawnmower.
