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.
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".
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.
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 / They Wasted a Perfectly Good Plot: 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. 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.
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.
