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.
Awesome Music: "The Lonely Man", both the solo piano piece and an uptempo version which plays during the opening credits.
Anvilicious: Quite a few episodes had An Aesop that was delivered with the force of a Hulk punch.
Designated Villain: Jack McGee sometimes comes across as this. Sure, he can be a jerk, but he's regularly treated like a scumbag when he usually he just wants to tell the public the truth about a destructive monster who (as far as he knows) killed 2 people.
Hilarious in Hindsight: Word of God explained that he wanted to change Hulk to red, but Stan Lee denied the permission. Years later in the comics, The Red Hulk became an actual character separate from the green Hulk.
Memetic Mutation: "Don't make me angry. You wouldn't like me when I'm angry". More often than not, it's followed up by "I don't like you now".
Nightmare Fuel: The series has been described as most frightening TV series ever for young children, with its focus on radical change into a creature making animal-like sounds.
Tear Jerker: The regular concluding scene in each episode of Banner hiking down the road to "The Lonely Man," ever burdened by the destructive curse he carries with him.
The Woobie: Of all the characters who fit this, it's David FREAKIN' Banner. At young age, he loses his mother. He loses both of his wives, one by car accident and the other by disease. And how does the series ultimately end? He dies at the end of the series finale. Worse is that his remaining family will have to learn about it.
When the Leader prepares to take the Hulk's power for himself, he orders Gargoyle to complete the apparatus needed to siphon the Hulk's power. We later see that he was playing Breakout on it, having presumably installed it out of boredom.
The "savage" Hulk after leaping out of a remotely detonated explosive by Doctor Doom, reacts to his (well, Banner's) cellphone ringing in his pocket. While it seems the She-Hulk is calling Bruce to see how he is, Hulk assumes the phone ringing means that it's about to explode, so he throws it far away.
Better on DVD: With the DVD, several deleted scenes are restored that help flesh out the characters through their interactions, such as Bruce and Leonard Samson having a tense talk about Bruce's history with Betty, or a short dialogue at Culver University where Bruce tells Betty how he worries that they experimented with the wrong motives.
Broken Base: The arguments about which is better: This or Hulk. Seriously, there are civil wars that have been less heated.
Hulk, while a tough cookie, isn't shown to be as unstoppable as he normally is. While it can be argued that this makes his conflicts more interesting, it's interesting to note that this is explained in story. Banner has been working on a cure while in South America, and recent testing revealed that the gamma within him is much lower, possibly explaining the Hulk's limited strength.
Captain America is a successful Super Soldier whose main weapon is a gleaming shield because he'd rather defend the innocent than punish the guility. The Hulk is a failed super soldier who breaks cars apart to make crude shields out of self-defense. Hero+Super Serum=shield user.
The incomplete serum is not a failure per se, but rather Gone Horribly Right by emphasizing existing character traits. Bruce Banner has anger management issues. Blonsky lives to fight. Johann Schmidt was an evil and ambitious Mad Scientist. Steve Rogers is a selfless Determinator accustomed to taking a beating and keeping his cool. Steve is the only one to get the formula as it was meant to be given (refined, in a lab, with someone who can handle it) which is why he is the only one that doesn't suffer horrific side effects.
At one point, Doc Samson mentions that it's a point of pride with him that he can always tell when someone is lying. Emil Blonsky's actor, Tim Roth, later went on to play someone who could do just that in Lie to Me.
Thanks to a brief shot of one of Ross' soldiers sitting with a long item attached to his back (he was really leaning against the vehicle's business-sized antenna), fans immediately assumed it was an Easter Egg, of Hawkeye's Early-Bird Cameo. Amusingly, Hawkeye (Jeremy Renner) and this version of Bruce Banner (Edward Norton) do appear together in The Bourne Legacy.
The last time we see Bruce, he's in hiding again, and his new daily regime involves drinking a bright red tea. In more recent times, the Roselle is discovered to have the ability to lower blood pressure, when made into tea. It is bright red. This leads to Fridge Brilliance: Remember all the times we see green drinks? This is a literal case of "red means stop, green means go".
Memetic Mutation: A gif of Banner closing his laptop has picked up steam in certain parts of the internet.
Seinfeld Is Unfunny: Tony Stark's cameo blew people's minds at the time with the idea of a shared movie universe being completely unheard of.
Strawman Has a Point: General Ross is wrong because he is obsessed with weaponizing the Hulk Out for an army of Super Soldiers. At one point, he says "As far as I'm concerned, that man's whole body is property of the US government". In a way, he is right: Banner tested the procedure on himself, and that automatically made him the government's responsibility, since the experiment was Backed by the Pentagon to begin with. Ideally, the solution would be to give Banner a place to relax and be humanely treated while they work on a cure/synthesize it. However, Banner is determined to prevent the Hulk from being weaponized, so he stays on the run until he finds a cure. Of course, Ross could have saved himself a lot of trouble if he hadn't lied to Banner about the project's purpose (radiation treatments instead of Super Soldiers) so he could recruit a knownTechnological Pacifist for such a project in the first place — except that he seems to believe that most scientists ARE Technological Pacifists in the Marvel Cinematic Universe.
They Wasted a Perfectly Good Character: This movie has the origin story of The Leader. He's had essentially zero presence in the MCU past this point despite being one of Hulk's arch-enemies and having very good villain potential.
