I felt that Jor-El's speech to Kal-El in Superman felt very Messianic.
Also, the whole El surname implies divinity.
On the other hand, the finale of
Superman (1978) is very much a
rejection of that equation of Superman with divinity. When faced with a choice between being
super and being a
man, Clark defies his Kryptonian father and uses his powers to reverse time and save Lois. Clark very definitively choses to be a
man over being a "god" in the 1978 film.
OK, so I signed back up for HBOMax and am getting ready to start Season 2 of Titans, which has once again reminded me of the fact that darker adaptations of DC comics characters is not a bad thing.
I could not stop laughing at the trailer for S1 of
Titans. Robin going, "Fuck Batman!"

It came across like an angsty 14-year-old's idea of sophisticated writing.
By contrast,
Harley Quinn seems to understand how to do "adult versions of kids characters" a lot better. And
Doom Patrol looks fun.
I have to admit, I'm honestly a little confused by why they still market superhero stuff to kids. I don't think any of the movies have had a rating lower than PG-13 in at least as long. I know comics used to be seen as a kiddy thing, but that hasn't been true since at leas the 1970s or '80s.
I mean, yes and no. I got back into comics in 1999, and while they were certainly trying to write reasonably sophisticated stuff in the main titles, they were also very clearly designed so that kids could still read them without it being totally inappropriate. And before that, I was given (and read)
The Death of Superman trade paperback as a younger kid in the early 90s -- there was
bit of blood but it was all very moderated so that kids my age (6 or so at the time) could still read it.
Detective Comics and
Action Comics and such were certainly things adults could read and enjoy without the story being "dumbed down," but children were still a part of the target audience too. That's why there were "for mature audiences" imprints like Vertigo.
Similar situation with superhero films. For every
Blade, there have been far more examples like
Spider-Man 2 or
Captain America: The First Avenger or
Iron Man or
The Avengers, with mostly sanitized violence and plots designed for both children and adults. Even Nolan's
Dark Knight trilogy is careful not to have too much blood or gore (to an unrealistic degree) so that kids can still watch.
Zack Snyder is really an outlier in his desire to make mainstream superhero character films for mass audiences that are actively
inappropriate for children.
