Eureka/YMMV

"Carter: "What were you dreaming about when it happened?"
 * Adorkable: Fargo.
 * Big Lipped Alligator Moment: Henry gets a random scene where he sings "She Blinded Me With Science" for, not to mention the whole laser light show, Fargo DJ'ing from his office, and everyone dancing. Then again, this was Fargo's idea. Should we really be surprised?
 * Somewhat Lampshaded: while trying to woo, Henry realized that   would already have used every play in his book, so he would have to do something completely out of character to impress her.
 * Cargo Ship: As of "Momstronsity",  Yes really; she even has shades of Tsundere.
 * Creator's Pet / The Wesley: No, seriously. The Wesley. Crusher. Wil Wheaton joins the cast as Dr. Isaac Parrish. Rather amusingly, as much griping as he did about playing a snotty Insufferable Genius teenager, apparently he's perfectly willing to play a snotty insufferable genius thirty-something as long as he's deliberately unlikeable.
 * Crossover Ship: Claudia/Fargo in Crossing Over.
 * Crowning Music of Awesome: Bear McCreary created the music for Liftoff. Enough said.
 * Crowning Moment of Heartwarming: The hospital scene in the episode Games People Play
 * Die for Our Ship:  seems this way, but the actor actually asked to be written off the show.
 * In season four,  Does this actually disqualify him from this trope?
 * Fan-Preferred Couple: Stark/Carter.
 * Later on, anyway. Early in the first season the two seem to genuinely hate each other.
 * They start as two completely opposed characters, then fire forged friendship kicks in and they eventually turn into an Odd Couple.
 * Genius Bonus: Vincent claims to have a Ph.D. in molecular gastronomy.
 * I Want My Jetpack: Dr. Grant actually complains that the Eureka of 2010 is too pedestrian (on first blush at least) by the standards of 1940s visions of the future. It's actually Fridge Brilliance when you realize that Eureka (and the US government) probably goes to great lengths to appear as nothing more than a sleepy little bucolic town should any uninvited out-of-towner make their way there and take too long to leave. Subverted upon meeting the robot deputy and going to GD; he is suitably impressed once he gets past the mundane exterior of the town.
 * Magnificent Bastard: Nathan Stark.
 * Magnificent Bastard: Nathan Stark.

Stark: "You know. The usual things... wealth... power... control... over everything..."

Carter: "... You dream about world domination?!"

Stark: "... Not all the time.""

"Carter: "Can your ego even fit in this building?!
 * As the show progressed, he proved to be more of a Guile Hero: he was a jerk, but he was also very loyal to Eureka, to Allison, to Kevin...
 * Really, he was still a Magnificent Bastard, just a bit more magnificent than before:

Stark: *nonchalantly checks the ceiling's height*"

"Kid One: That was pretty sappy.
 * MST3K Mantra: Ninety percent of the "science" is Techno Babble BS that contradicts real science on nearly every level. Doesn't make the show any less enjoyable, though.
 * Best summed up by Carter: "Is it Eureka possible?" (The answer is usually "Maybe.")
 * Tastes Like Diabetes: In show reaction to Sheriff Carter's Christmas Story

Kid Two: Yeah, I'm pretty sure I got a cavity."


 * Tear Jerker: More than once. "Once in a Lifetime" is particularly poignant.
 * The death of  in "Right as Raynes", particularly Stark's reaction.
 * Stark's message in the logic diamond in "Show Me the Mummy". Sob. It was this episode that really made it hit home.
 * Fargo realising that Jack lied to him in "Force Quit" and that.
 * And a couple episodes later, when  That entire storyline is made of tearjerker.
 * Took a Level In Jerkass: After Series 3, Allison frequently comes across as a Bitch in Sheep's Clothing, more and more. See Unfortunate Implications for her attitude to finding her son no longer has Austism in Series 4 and over-the-top reaction to the Jo/Carter Ship Tease during Series 5, despite the fact that Carter clearly has been in love with her since day one and they are currently in a committed relationship. He even frigging proposed to her!
 * Trapped by Mountain Lions: Allison spends most of "Reprise" rescuing a man completely unrelated to the plot.
 * Ugly Cute: The little robot in "Momstrocity". D'awww!
 * Unfortunate Implications: When Allison admits to preferring Kevin "this way" in the new reality. Did we mention that in this reality he no longer has Autism?!
 * Though it's YMMV, what parent wouldn't give anything to have their autistic child be able to function without help? One really cannot blame her for liking the ability to connect with her child when she couldn't before.
 * While this is perfectly valid argument, it still has a subtle undertone that Original!Kevin was somehow defective in the previous timeline. While any parent with an severely autistic child like Original!Kevin would desire that sort of connection with their child, the fact remains that she should love Kevin no matter what. By showing a clear preference to New!Kevin, she shows a great disservice to Original!Kevin who's only problem was that he was unable to communicate with her. As we saw long before Series 4, Original!Kevin was just as smart as New!Kevin.
 * Also, could one say the same that her preference to New!Kevin would be justifiable if the Original!Kevin had say, Down Syndrome, in the original timeline?
 * The Woobie: Henry. Nothing ever seems to go right for Henry, the hardest working person in the town.
 * While Jack is more of the Butt Monkey/Chew Toy -- i.e. most of the things that go wrong for him are played for laughs -- he definitely has his woobie moments. The ending of "Unpredictable" is kind of heartbreaking: Allison is reconnecting with Nathan, his ex-wife is taking Zoe back to L.A. with her, and he's all alone in the middle of a crowded room.
 * Jo is staring to get this treatment in the fourth season.
 * It's alright! She gets a wonderful new house...
