Last Bad Dialogue Trope from Round 2
Is Clunky Comebacks or Other Wise known as Trash Talking opponents is and can be a form of bad dialogue if it is not used correctly. The Trix witches are guilty of this Bad Dialogue trope more than anyone else. Darcy falls into this way more than Icy and Stormy ever fall into it.

Icy does it the most in Season 1 arc finale fight with Bloom in the 4kids Season 1 version of it. And this one is completely natural for both characters villain and hero they both trash talk each other aggressively they've been aggressive towards each other for a lot of the first Season. Icy's trash talking is why she ends up wasting her energy and is a reason why she never uses it again a whole lot in later seasons especially against Bloom because she knows Bloom distracted her that one time while instead of focusing on better spells she foolishly wasted her time and energy on trying to cut Bloom down by insulting her. The point is the trash talk between Bloom and Icy is as believable as the trash talk between Musa and Stormy in the episode Battle For Eraklyon in Season 2. Both girls and their opponents in both scenes are equally aggressive in words and deeds.
Darcy's trash talking though with Stella in that fight at Alfea at the Beginning of Magical Adventure is shallow and fluffy on Darcy's side of the trash talking she does not sound like herself throughout the whole fight whereas Stella sounds too natural and the whole moment just feels like this is funny but why is it even happening? Darcy's not publically aggressive she's sneak aggressive and she's always been so.

But we'll get to the previous chapter's video of Bad Dialogue Trope Clunky Comebacks first Bad Example about Clunky Comebacks and yes DC finally messed up on of their favorite Superheroes from their beginning times in an actual live action film, Batman: The Dark Knight. Batman's script for some reason gives him the worst comeback line of all in the movie and one that is not linked to the person and superhero we know he really is deep down inside. It doesn't do the superhero character just.

Just read it for yourself

Bane: "So you came back to die with your city."
And now see what is wrong with Batman's reply as the comeback here: "No, I came back to stop you."
Batman would never just say things so literally that is part of his mystique and why some people scratch their heads at his actions because he wants to keep you guessing with what he might be saying in other movies and shows the words, "I'm Vengeance!" is a way better comeback line and we know this is linked to his identity because he has gone toe to toe fighting off superheroes not just pyscho villains like Superman is one of the many Superheroes who has an aggressive temper issue and mood-swings and Batman is willing to get slightly aggressive in order to make sure the day or night in a city is saved whether it be from a brainwashed superhero or a pyscho villain. The line "I'm Vengeance!" gives indication that one he always brings karma along beside him and his aggressive level has risen due to the damage a villain of superhero has done accidentally or intentionally, Skylights. Batman is always willing to get more aggressive than he can be and that is the subtext of the "I'm Vengeance" meaning behind it.

An even more excellent comeback is having your hero not answer your villain with words but just action as Luke does in Empire Strikes Back when Vader addresses him before their first lightsaber duel. Luke never bothers to respond by words he stays silent and jumps to real action of the lightsaber battle. This the best comeback you can get in any story and movie. Actions say a lot and can fill in for a lot of what would be considerable filler dialogue both in screenplay and fantasy novels too.

Round 3 Tropes of Bad Types of Dialogues

1. Forced Comedy Marvel Universe especially Thor involved movies sometimes go way too ham on dark comedy or general comedy antics when other things could be mention that are more relevant to the storylines. It is just a little over the top too much comedian, Skylights. And I'm talking about the comedy with Thor when he meets the Guardians of the Galaxy team.
Granted both characters are genuine funny in their own movies but the humor between him and Rocket kind of overwhelms the truth seriousness the film began with and the Guardians of the Galaxy's real mission. Granted if Thor and Rocket had more of a duo show the humor between the two of them would be as absolutely necessary as it is between Thor and Loki in the Thor Movies of the Marvel universe my problem are the jokes between Iron Man and Captain America. I am totally okay with Captain America but never once would I ever think Iron Man would ever get any joke anyone says to his face I mean come on he is such a gruff man honestly why would he joke about anything? It just doesn't sound natural to make him be around jokes or try them out himself. Regardless of what your opinion is there is such a thing as over the top comedian behavior.

Yes there is an actually problem between the exchange Dialogue of Kylo and Poe in The Force Awakens the 1st of the sequel trilogy of Star Wars Poe is acting way too much like a comedian here in front of Kylo Ren and it damages the tenseness of Kylo Ren's introduction scene. This was just over-scale stupidity, sweet Skylights. And besides what's the point of Poe's comedy here if he never uses it again to try lighten up an actual dire situation in the rest of the trilogy.

This right here is added dialogue that falls into the Abandoned Subplots plot hole, truly friends because Poe never has a comedic side in either of the other movies in fact the comedic role falls to Finn who plays it better because being unknowledgable as a previous storm trooper of what the rebels actually do makes him seriously funny and socially awkward around everyone else and it's very hard to hide his stumbling around through worlds. We're used to seeing stormtroopers being ruthlessly clumsy to themselves but Finn gives a whole perspective of what it feels like to react to his own clumsiness from his previous life meeting him up in his rebel life. It impacts Finn's history and background.
The other good example is Vader's confrontation with one of the rebels aboard Leia's ship the Forced Comedy in A New Hope here is excellent and fits the situation and covers the attack and defend portion of what makes Good Dialogue good, sweet Skylights.
