Lol, I'm still not understanding the big deal about all this. Yes, I know Jimmy is a big character in the Superman mythos. But I don't see why it matters whether he's dead or alive in the DCEU if he was never going to play a significant role in the first place.
I think it's part of a larger issue people have with Snyder, where they don't feel he shows enough reverence or respect for the mythology. I get it, though it doesn't bother me really.
I think the thinking was "Well, we don't need Jimmy Olsen, so let's put his name as an Easter Egg for the fans, to shock them, subvert expectations, and basically say 'This is a whole new Superman story'"
Very short sighted if you ask me. Best case scenario: people love the film, the ones who don't care about the mythology don't care at all about the Olsen twist, the ones who do care, are just okay with the choice, maybe some fraction of a percent actually think it's fun or enhances the film in any way. BUT, let's say a large section of the fans don't like the movie, which was always a possibility, they're gonna use that as ammunition that Snyder is disrespectful to the mythos, and he's basically saying "F*** y'all and your Silver Age BS, this is MY story!"
Reminds me of Stanley Kubrick doing an adaptation of Stephen King's The Shining, King wasn't happy with some of the choices he was making and changes to the story. In the book, the family drives a yellow Volkswagen, I think it was. In the film, a character is driving in the snow and passes by a wreck on the highway, an overturned, you guessed it, yellow VW. It's widely interpreted as Kubrick's little FU to King, "There's your characters, this is my story!"
I don't think Snyder's choice was meant with those intentions, but the point is, that choice could easily be interpretted that way.
It's one of those head scratching decisions where you think "What did they possibly think they were going to gain from that?" Like not making Doomsday look faithful to the comic version. And this is coming from someone who really likes the movie. I just don't think it was really gonna have anybody like "Now I realize anything can happen!" And make them watch the rest of the film from any different point of view. Maybe if it was Eisenberg and they kept him as just Jimmy Olsen journalist, but Idk.
For me, I think they could have benefitted from an Olsen character somewhere, even if they just had him kind of hanging around in the Planet scenes. Easily could have worked him into the Perry White battle of Metropolis scenes in MoS, and it could have added a little humanity to Clark's character down the line, a buddy he could have a beer with, similar to Matt Murdock and Foggy Nelson. It's not like he had to be some "Aw shucks, Golly gee" kid with a camera around his neck, just a regular bro for Clark. Dude could use a friend. I believe Jimmy even had his own comic line once, Superman's Pal Jimmy Olsen. That's a pretty big part of the Superman mythos. You're already taking a risk with Batman's No Kill code. Why push the envelope?
My worry is that they feel like there's no need for Jimmy because they are cutting off the Clark Kent, Daily Planet Reporter persona, which would be a real loss for me, depending on where they're going in the future. I worry that they took the view, it's silly that nobody recognizes Superman behind the glasses, that could only last for so long, so we'll incorporate that aspect of the character at first, and then move on without it. Hope not.
