Yeah, Hal "Harlequin Lead" Jordan who took advantage of Power Girl only to have it hand waved away, had a relationship with a young girl who aged herself into an adult, and was just a boring asshole.
Kyle Raynor was the kind of every man Green Lantern who appealed to people, that his creator made in the hopes to set people off of him and make them bring back his beloved Hal Jordan. By making him the Anti-Hal, and then when they had the chance to bring back Hal they did everything they could to dump Hal's baggage on Kyle while absolving Hal of every sin he every had.
Which led to the shit show with the "Entities" to explain away Parallax and ensure that Hal wouldn't ever be blamed "because he was a poor misunderstood adult who was a raging pretentious ass", and that ended up fucking up the whole mythos.
I mean the sheer stupidity of the whole thing, he didn't go insane from the sheer trauma and inability to do anything about it... It was all the Fear Demon! He wasn't prematurely grey! It was the Fear Demon! He didn't kill all the Green Lanterns! They were just unconscious!
Then there was the bullshit of purging Guy Gardner of his Alien Heritage! I am surprised they didn't have the ring turn Stewart WHITE! It was the stupidest nonsense I ever saw!
I mean Kyle gained the full power of the Battery, called himself Ion, and then decided to return it so that the Green Lanterns could eventually return with Guardians who learned to be more...compassionate. Just like Hal maddened by grief and the power called himself Parallax, it was just a stupid name!
But no, they had to do the whole entity thing to excuse Hal's fall from grace so that everything would go back to the status quo, and of course they assumed it would be popular by trying to portray him as...cool.

Let us not forget the shit show they did in order to bring Barry back, unseating Wally who was in the role so long that people only remembered Barry because of how Wally would go to him for advice or remember things that Barry had told him. Barry had basically become like Jay, a flash of yester year.
Of course they also had to do the whole "the Speed Force belongs to Barry!", he was the origin of all Speedsters, and "just cause we say so!" As an explanation for why Barry can reset time, mess things up for everyone, and can do anything with the speed force better than anyone else...
What did they do, unseat Wally through time, and wipe out his family. Try to replace him with a token black Wally after race swapping Barry's wife, brought him back reluctantly only to portray him as villianous, crazy, or out of control...
That was the main problem that comics had in the nineties and two thousands, die hard fans came in as writers, and tried to metaphysically turn back the clock to their own childhood. No matter how much damage they did to the character, how insane their plans for them were, and the ones in charge just sat back and let them do whatever.
Good example is Superior Spiderman which was an official SI fanfic about what the writer would do if he was Spider Man, wrapped in a power fantasy where he was never wrong and incapable of being toppled... Sorry I just hated that storyline sooo much, especially since Doc Octopus was shown to be incredibly strong and tough for his size, and he would have to be the amount of time he had those arms hanging in the air and all of them had to be a hundred or more pounds a piece...

Sorry about that, those things are what set me off reading comics...
My only other annoyance is their incredible drive to erase Tim Drake, for example how in every cartoon they weld on Tim's characteristics to Dick because a lot of people grew up with Tim as Robin, and they want to make them to see Dick as superior or something.
I mean in the Bat Family Dick has always been the athlete, the gymnast, and the ladies man. He is passable as a detective and as a hacker, but he never had the knack for it. Basically he was the guy who jumped in feet first into the action when the fighting started, but largely he could be very stealthy before then.
For some reason they just can't let him be himself in these things, he was always the guy who hated waiting when it was something like paperwork or boring stuff like research on the computer.
It is why Tim Drake in Young Justice kind of came off as one note and a lame duck, because they fused his good qualities with Dick to make him look like the best thing since sliced bread. With Tim looking like a joke in comparison.
I mean think about it, Tim was one of the founders of Young Justice alongside Bart and Connor in the comics, and for the cartoon they made Connor Dick's friend, made him one of the founders of the team, and of course...made him the super hacker/detective...
