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.
Anvilicious: Alpha terrorism can't be solved with "more money, more guns, or even a bigger prison," but "an end to secrets," which "will hold both sides accountable for the actions." Does This Remind You of Anything?? Massive secretive spending + heavily-armed secret police + torture-heavy secret prisons = The War on Terror. Rosen's saying that yes, terrorists are bad, but the solution is not to sink to their level but to force them to a higher one - treat them like common criminals subject to due process, not cold-war supervillains who need to be slaughtered wholesale. Terrorists want terror, and few things are more terrifying than that which is purposefully kept unknown. Stanton Parrish was expecting a secret war that would enable him to manipulate his enemies through fear - forcing the conflict into the light shows that Alphas are often just as pitiful as they are terrifying. Just like how the majority of terrorists are pathetic losers who happen to have guns. While terrorists are swathed in secrecy, they are comic-book supervillains. Strip them of their mystique and they're starving criminals.
Ensemble Darkhorse: Gary was easily the most popular character in the series due to his cool power, many funny moments and quotes, and for Ryan Cartwright's great depiction of a high functioning autistic adult.
Skylar was also very popular, and being played by Summer Glau sure helped.
Fridge Horror: Anna's DDoS attack on Gary was the equivalent of tasing his brain. No wonder he collapsed in sheer agony.
If you pay attention to the screen, it was actually a Sensory Overload that she performed. Still Fridge Horror, but much worse because imagine what he deals with daily. Hundreds, if not thousands, of people every day use phones, laptops, TVs, and other such devices that he can detect and still function with minimal harm. Yet one laptop instantaneously caused worse pain than a satellite dish did over a couple days.
It's the difference between living half a mile from the airport for 10 years, or standing on the runway right behind a 747 as it takes off. The former is annoying, but bearable; the latter, not so much.
Les Yay: In "When Push Comes to Shove," Nina uses her power to mentally force Rachel to make out with her. Although it seems to be less about this than overloading Rachel's senses to incapacitate her.
Magnificent Bastard: Despite showing up for only a few minutes in one episode, Stanton Parish had firmly qualified for this by the end of the first season. And lived up to it in the second.
Paranoia Fuel: So much of it! Next time you answer your phone, you could end up brainwashed into killing someone. A random stranger can convince you to do anything she wants with just a few words and a little eye contact. A seemingly harmless autistic person can actually be reading all of your texts and e-mails right now.
Special Effects Failure: Though the show does an admirable job depicting the speedster Alpha alongside the normal-speed regulars, it drops the ball when Rosen is speaking to him at the office. The two are on-screen side by side, and the speedster is clearly not really in the shot with Rosen, an effect not helped by the fact that the super speed effect is being achieved by fastforwarding his half of the scene slightly.
Warehouse 13's characters include Steve, a Living Lie Detector; Pete, who has Spider-Sense; Leena, who has Aura Vision; and Claudia, a Gadgeteer Genius. Which Warehouse 13 character crosses over? Dr. Vanessa, the completely ordinary side-character, whose sole appearance was only a cameo that only served to establish the shared universe. Especially odd in that Steve was introduced to Warehouse 13 the same day that Alphas premiered, practically foreshadowing a future crossover.
No crossover with EUReKA ever happened.
What an Idiot: In The Devil Will Drag You Under: Kimi ... You should've known confronting Bill Harken by yourself was not such a great idea.
