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?: When Rick becomes A-Bomb he's eager and excited while Hulk wonders why he isn't freaking out at his transformation.
Big Lipped Alligator Moment: In "Abomination", Red is searching the facility for Abomination. He comes across a floating figurine of a man in a yellow dog suit. It turns out to be a bomb, but Red never questions the figurine.
Broken Base: It's either a fun show with a great cast, or a good cast being put to waste in one of Marvel's worst shows.
Even those who don't like the show will admit that Red Hulk is the best character. She Hulk being a close second mainly because of her voice actor.
Ho Yay: Between Hulk and Thor, of all people. At one point, Thor deliberately insults Hulk in an attempt to incite his rage. Hulk calls him on it, and the look on his face as he replies sounds...almost flirtatious.
Thor: What can I say? I like you when you're angry.
Idiot Plot: "Monsters No More" turns the entire town into gullible morons who turn on the Hulks in a second and turns the Hulks into a bunch of vague idiots who never tell the panicked townspeople that there are bombs in the city.
Narm: In a hilariously cheesy scene in "Galactus Goes Green", the Hulk is trying to convince a brainwashed She-Hulk to snap out of Galactus' control. This leads to a very awkward line from She-Hulk.
The frame-skipping animation and the sliding scene panels (meant to simulate a comic page) can be very distracting for most viewers.
Planet Hulk. Which was probably intended to look awesome, but comes off looking like a green Geodude.
Older Than They Think: Having a fairly intelligent Hulk who never reverts into Bruce Banner is something that the comics did as far back as the 1990s when Banner created the "Merged Hulk" (also known as the Professor Hulk) persona. The cleverness exhibited by this version of Hulk also resembles the cunning "Green Scar".
Scenery Porn: The winter landscapes in "Wendigo Apocalypse" are surprisingly beautiful, and set a good atmosphere.
Special Effects Failure: Annihilus' insectoid alien swarms in the first two pilot episodes are often just non-animated drawings zooming in at the screen. Then the episode "All About the Ego" brings us Ego the Living Planet, a horrific, badly rendered, CG cell rendered abomination.
Hulk's heart-broken rage towards the Leader apparently killing his team in "Into the Negative Zone".
Deathlok is a pretty tragic figure. He's lived his entire live in a horrible future where humanity is on the brink of extinction. He notes that the main reason he went to the past, aside from stopping the Skrulls from destroying the planet, was to see the sunlight and the beauty of Earth before it was all taken away.
Made even more heart-wrenching when his cybernetic contact informed him that his mission failed. His last resort? Killing himself by self-destructing his body to blow up the Skrull ship, and he was happy to do this knowing that he wouldn't have to live through the horrible events that the future holds.Damn.
The Planet Hulk two-parter had a couple.
Hulk losing his temper again, and nearly throwing the Leader out the airlock for almost killing his family (again).
Ego the Living Planet, while not exactly the type to route for, is fairly sympathetic in the season two premiere. Not only did he keep his promise not to harm other worlds, but he was willing to die in order to kill Galactus with the Kree cosmic bomb attached to him, and because no one in the universe loved him (other than the Hulks). Poor guy.
The Scrappy: A-Bomb was supposedly intended to be the Break-Out Character, but a lot of people find him annoying for the most part. It doesn't help that Red Hulk seems to have taken his intended position and is considerably funnier.
They Changed It, Now It Sucks: Mainly due to the creative liberties taken by the show, some more creative than others. This includes, but is not limited to:
She-Hulk was changed from a strong, confident lawyer into a stuntwoman with a chip on her shoulder.
Devil Dinosaur, a lesser-known Jack Kirby creation, was reduced to the Team Pet they picked up in the Savage Land. Many fans didn't appreciate seeing a fan-favourite character being reduced to the status of pet who acts like a big friendly dog.
Doc Samson is being portrayed as a snooty, unpleasant generic psychiatrist used for comedy rather than a Gentle GiantGenius Bruiser.
They Just Didn't Care: The series is rife with unremarkable animation, but the largest actual error between the dialogue and the animation is in "The Collector," where She-Hulk can't read the "alien-jerk-language'' on a control panel. Said language is actually just sets of random numbers like "382308."
They Wasted a Perfectly Good Character: All the characters have interesting elements or story arcs in the comics that made them work in the first place note such as Skaar being Hulk's son, She-Hulk's personality and unique status as a superhero lawyer, or Red Hulk's past feud with the Hulk as well as his redemption story arc . With the apparent exception of Skaar, all those elements are either ignored, overlooked, or unexploited.
They Wasted a Perfectly Good Plot: It's been pointed out that the idea of a team of Hulks endorsed by S.H.I.E.L.D. fighting the universe's greatest threats with a "webshow" aesthetic could have been an interesting idea if they had used any of those elements to their fullest potential. Instead, they go halfway with all of them.
Ugly Cute: The Goom babies from "The Hunted" are just 4 little adorably ugly critters.
Uncanny Valley: The level of detail on a small girl's face (coupled with her obviously-adult voice) gives the character a slightly unnatural appearance.
The Leader's small posture and surreal head design seem to give him an eerie presence.
The Woobie: The Hulks. Hated by the world for their destructive power and imposing image.
Solidified further in "Monsters No More" they're tricked into destroying Vista Verde, whose population are among the few who genuinely care for the Hulks.
