There certainly are issues with the film, most of them execution issues, but most people actually have praised the story elements from what I've seen.
It's precisely because it's a better story than a lot of the garbage we've seen recently (i.e. Green Lantern) that I find the mistakes so frustrating. It really seems like if Goyer had handed that script to another talented writer (he's on good terms with J. Michael Straczynski for example), and asked him to polish it for four weeks... we would have had a grand slam. I don't think the movie is that far off:
- hire a dialogue editor
- remove the giant metal spider in the Indian Ocean
- a few more scenes involving Martha, Jonathan, Lois
- Some acknowledgment of the destruction at the end
- Make the Jor-El/Zod fight more coherent
I still voted the movie 7/10 on imdb. I see a lot of problems, but it's a step up from the rest of the genre. Most of the problems in the film, in my opinion, are due to the script. I blame Goyer.
I've never heard anything about the parental elements being criticized 'aggressively'.
Agressive refers to the general criticisms, not specifically the parents.
The most common criticism I found of the movie, in numerous reviews, was that the first half was better than the first half, and of course other criticisms that mean almost the same thing, such as "too much destruction".
The audience doesn't need to have them all share screentime equally in order to tell the story at hand.
The audience doesn't "need" anything. However, it wants to be entertained and moved, and the previews were promising a movie that would be intellectually stimulating and be a coming-of-age story. Instead, they got inconsistent world building from Goyer, and an action-packed pop corn flick in the legacy of 2012 and The Day After Tomorrow.
Jorel was so important cause he was Clark's final link to the past, which he ends up giving up to save Earth by the end of the film. Sure Goyer COULD have had Lara also be a 'ghost in the machine' but how does that actually improve or enhance the story? Now you've got two characters you're trying to develop in an already very full movie when only one actually is needed to get the story through to the audience.
It's either a plot hole that Lara doesn't show up, or it makes Jor-El look like a prick. If it doesn't bother you then that's fine, but it shows up in a litany of criticisms as a "WTF?" moment.
It would have actually made more sense to have only Lara than to have only Jor-El. Jor-El's absence could be excused by the fact he was killed off right before he was going to make his USB-brain. It would also better explain Superman's character to the audience, to see the other half of his nature.
If the movie was supposed to be about Clark choosing Earth over Krypton -- and it does look like that -- then they should have shown more happiness from Clark on Earth, so that it makes sense for him to choose EArth. Instead, he lives a lifetime of bullying and as a loner, and finally a priest told him to choose Earth as a "leap of faith", i.e. a meaningless choice. As Snyder himself said, humanities doesn't have much to offer Clark, and indeed that's what they presented in the film.
Oh yeah, add that to the list on top, the priest scene was dumb. Nobody would ever go to a random priest, it was just Goyer trying to force his failed Jesus metaphor.
