Audience-Alienating Ending: As a result of the series being cancelled, the unintentional series finale is nigh-universally derided for being a massive drama filled mess that reeks of the Conflict Ball. Paige and Walter break up as a result of Walter lying about going to an event with Florence leading to Paige accusing Walter of intellectually cheating on her, Sly quits out of outrage at the fact Florence is in love with Walter when he was the one in love with her, and Toby and Happy quit both out of solidarity and Walter snapping at them for having warned him, all while Walter all but regresses his character development and fully displays his Lack of Empathy, causing the series to end as the remnant of Scorpion and the newly formed "Centipede" are now no more than bitter business rivals. Not only do many find it hard to find any of the characters sympathetic in this whole mess when it's their own personal flaws rearing yet having them blame everyone around them instead, but it comes off as so forced after an already lackluster season that it just feels hollow. Not helping matters is how the narrative seems set on vilifying Walter as if he consciously chose to cheat on Paige or steal Flo from Sly despite it being a single white lie that snowballed out of control, as well as a case of Just Friends with Walter not "seducing" Flo as Sly accused him of, while absolving everyone else that knew about it and didn't tell them like Happy and Toby.
Designated Hero: A lot of times, the team comes across less as heroes, and more as crazy people trying to fix the messes they caused.
Fanon Discontinuity: There are more than a few people who prefer to consider Season 3 the end of the series. See below for details.
Genius Bonus: The show's logo includes such things as a Fibionacci spiral as the stinger.
Harsher in Hindsight: The entire Season 4 finale, after CBS decided to axe the show. The series ends on an all-time sour note and fans' only hope is that it will be resolved in a crossover with one of the other shows it shares a universe with, although unlikely at this point.
Hilarious in Hindsight: In "Sharknerdo", when Walter and Paige are adrift at sea with little hope of rescue, Walter mentions 'Brandy' by Looking Glass, saying that the sailor who returned to the sea instead of staying with Brandy 'was an idiot'. Flash-forward a few months to a specific film's release, and it sounds like Walter's preemptively insulting Ego.
Informed Wrongness: During a case where they needed to seal a section of garbage on the sea together and invited their neighbor Florence after she offered her sealant to keep it together, the section is surrounded by deadly Jellyfish that were attracted to ingredients in the sealant, and Florence is blamed for not knowing Jellyfish would eat it. However, it was never stated that those Jellyfish would be in the area, and as Flo makes clear, she is not a biologist and would have no way of knowing what a specific type of Jellyfish would find appetizing. Despite this, Walter, Happy, and especially Paige all blame her. In fairness though, Florence's attitude makes her come off as abrasive, something the team isn't use to dealing with outside of themselves.
The fact that people are still swinging golf clubs sending golf balls on a highly visible van. In real life, most people would see a van and stop so they don't hit the car because they could get kicked off of the range for that.
One episode had Cabe Gallo emerge from the water on a beach (It Makes Sense in Context). The framing of the scene clearly aims for maximum coolness (a couple of girls on the beach stare in awe at him, and the way he emerges in an Unflinching Walk is a clear Shout-Out to Robert Patrick's role as the T-1000) ... except that the scene is set to "Aserejé (The Ketchup Song)", the 2002 One-Hit Wonder (in a series made in the mid-2010s) best known for its nonsensical chorus and the dance craze associated with it (granted, the scene avoids using said nonsensical chorus and instead uses the song's intro, but still).
One-Scene Wonder: Mark Collins, the team's former Token Evil Teammate (until they had him committed), has appeared in only one episode so far ("Plutonium Is Forever", however he has been bumped up to a two-episode role as the final villain in Season 2). Still, he's popular enough that he not only has a section in the character sheet, but that section has more tropes than the one on Walter's sister Megan, a Recurring Character.
One True Pairing: Try to find one fic that doesn't ship Walter/Paige, Toby/Happy, or Sylvester/Megan. Although it should be noted that Sylvester and Megan had a completely normal, healthy and happy relationship right up until her death, Happy and Toby are now officially married, and Walter and Paige finally seem to have gotten their act together as of 'Marooned 8'.
Portmanteau Couple Name: "Quintis" for Toby and Happy (which Toby has used himself a few times) and "Waige" for Walter and Paige.
The Scrappy: Patty. Basically a precocious Alpha Bitch who does nothing but annoy people by being totally self-righteous and rarely sympathetic. With a Christmas episode where she's everywhere in Walter's disoriented imaginings, people had even more reason to be nauseated at her character when forced to take her up to their eyeballs.
Seasonal Rot: Season 4. The show began running on almost nothing but Conflict Ball generated by Florence, introduced Patty, once again tore apart the team and began to repeat Season 3's events with massive character derailment from Walter as he went from in a steady relationship with Paige to being the guy who once again makes decisions thinking only about himself and not how the consequences will pan out, everybody is complaining once more, and audiences got sick of it.
So Bad, It's Good: The show leans on Artistic License – Physics (and in a few other scientific departments as well) frequently enough that it's distracting. It's also quite hilarious, and the cast work well enough that the viewer can let it slide. Granted, realism was always going to be an optional extra on a series from people whose collective CVs include Prison Break and assorted entries in The Fast and the Furious series.
Special Effect Failure: The episode with the silo features some hideously poor CGI. A silo is caught with a net, never keeps going, and someone holding onto the ledge never even so much as budges despite physics saying he probably should.
Strawman Has a Point: Paige is presented as in the wrong for quitting Scorpion but considering the fact that associating with them caused her son to nearly be incinerated, added to the fact that Happy was more angry at the fact that Paige leaving ruined the dynamic showing a remarkable amount of apathy and it is very understandable why Paige would want her son far away from them.
