Who, in your mind, are the worst versions of Superman? Mine, in descending order:
Injustice Superman: This one's pretty self explanatory. They turned him into an outright villain. I have a hard time believing he'd be this easy to corrupt. Even if he lost it and killed the Joker, the idea that he'd go all dictator and take over the world and see everyone as his "subjects" within just five years time is a bridge too far for me. Justice Lords at least tried to imply there was a lot of stuff we didn't see leading up to Superman's corruption and even then he came across as more concerned with public safety than iron handed rule. If you read the comic, you can see how Superman became a dictator and it still doesn't seem to follow a logical pattern.
DCEU: I've gone over before why this version bothers me. I left the theater practically traumatized by his killing of Zod. Pa was willing to let a bus full of kids drown than risk Clark reveal his powers. Lois finding out from day one about his secret identity wasn't exactly a good selling point but I suppose if they were going to do it eventually they may as well have gotten it out of the way early. The destruction porn was probably worse than the death of Zod. Him kissing Lois in the middle of a city where half the population was essentially killed was just kind of tacky. The overall tone and darkness just didn't work for Superman. They had some clever ideas like him having trouble breathing when he first arrives on Earth or having the fortress be an old Kryptonian scout ship (with possibly Supergirl on board) but overall I just didn't like it. I'm hoping JL makes up for a lot of this.
DCAU Superman: This is a controversial entry, I know, but I think he was handled poorly here. He was deliberately de-powered by the same people who redefined Batman for an entire generation which just makes it look like they are trying to undermine him in comparison. This problem only got worse as the progressive series' went on. The JLU more or less made him a punching bag. And when they weren't doing that, they just made him a "punch first and ask questions later" guy. Like with Captain Marvel. He was the easiest of the team to manipulate. Yes, I'm aware of the "world made of cardboard" speech. That doesn't really make up for a decade of making him a muscled rube. This bad portrayal culminated in Batman Beyond where he was controlled by a Starro for what is implied as more than a decade. The comic says Lois died during that time. Taking an even bigger dump on him just for good measure. I WANT to like this version but I just can't.
Lois & Clark: This entire series just seems like it was poking fun of the Superman mythos. We get it, a pair of glasses isn't a good disguise. And as the series went on, they just went more and more off the rails (frog eating clones, anyone?). I kind of liked it at the time but it hasn't aged well.
Young Justice: Overall I loved this series and universe in general. It had all the right elements. But their treatment of Superman in the first season really grated on me. I have a hard time believing he'd treat anyone the way he treated Superboy in the first season. All of this was, of course, to make Batman look like the better father figure. Their relationship improved greatly with the second season but his treatment of Superboy in the first was a bad blotch on his record. Wonder if he'll even be in the third season (probably sans trunks).
Kingdom Come: I kind of like this version in that I can see why he did what he did (and he certainly handled Lois death better than Injustice did). But he still abandoned humanity. Now, I chalk a lot of that up to him losing Lois, and he eventually did the right thing, but, like YJ, it's still kind of a blotch on his record. The flip side of this is that he has been portrayed better in spin off series than he was in the original book where it just felt like he was being led around by WW. JSA made him seem like an elder statesman. And the Convergence book where he teamed up with Superboy really made him come across as more of a father figure than he had ever been. Plus, he has my favorite Superman costume!
Supergirl: This one's pretty far down the list for a reason. As a stand alone Superman, he's about perfect. Both his Clark and Superman are spot on! But it's obvious they go out of their way to undermine him to make Kara look better. He gets mind controlled in the first season even though she didn't to make her the hero. He gets mind controlled AGAIN in the second season to get him off the board. And then he turns around and says that she's both stronger and more noble than he is. We get it, it's her show. And then, to top it all off, they have Flash poke fun of him in the musical.
Honorable mention, and I haven't read much about either one so they aren't really included here, would be Red Son Superman and Nazi Superman. Both show remorse for what their respective governments did but didn't do much to make amends for it. Just a "softer" version of more of the same.
I've tried to exclude mainstream comics versions from this list because I have my varying degree of issues with all of them. DC continuity, and Superman's in particular, is an unstable mistress and if I have an issue with it, it's that. You get attached to one thing and five years later it's not canon anymore. I have no reason to believe that won't be the case five years from now either. There has never been a "perfect" comic version (outside of maybe the Smallville comic but that wasn't canon). Feel free to include least favorite eras if you wish.
