Krypton did have it's chance though. The Kryptonians are the ones who ravaged their planet to the brink of destrcution. Kryptonians are the ones who, as their planet was shaking beneath, and falling apart, decided to do nothing about it. The Kryptonian government (in every era from the Golden Age all the way to MOS) knew the planet was doomed and did nothing to try to save the population. That's the story of of Krypton though. They were advanced race of people, but destroyed themselves out of their own myopism and hubris.
No race is a monolithic "they" marching in lockstep, except the Borg or something. Would you condemn the rank-and-file Kryptonians for the poor decisions of the small elite that happened to be running the government and military? That's always a shortsighted way of thinking. Remember that Superman was created by the sons of poor immigrants and was initially portrayed as a populist, working-class hero who defended the little guy against exploitation by the elites. Clark Kent grew up on a farm. This is not a person who would focus only on the decisions of the people running the government and dismiss the ordinary citizens as collateral damage.
(See also
Doctor Who and Gallifrey. "The Day of the Doctor" and "Hell Bent" were about the Doctor deciding that it was wrong to condemn the ordinary people for the decisions of the corrupt leadership, and ultimately doing what he's always done, siding with the little guys against that corrupt power. Would Superman do any less?)
It's not pretty, but when you want to hold to the story that Superman is "The Last Son Of Krypton", the other billions of Kryptonians have to bite the dust, somehow.
But that doesn't mean it's a good storytelling choice to give Superman the option to bring his people back and decide to condemn them to extinction himself. That runs against everything Superman has ever stood for. He's the last son of Krypton by a circumstance that he would move heaven and earth to change if he could, but the one tragedy at the core of his optimistic story is that his own people are the ones he can't save even with all his power. Give him the power to save them and have him refuse, have him assume that his power gives him the right to dictate life and death rather than an unambiguous obligation to protect life, and he ceases to be Superman and becomes Zod.
I loved the Nolan films but I'm having trouble accepting Wonder Woman, Superman as all part of one universe.
It has always been thus with comic-book universes, especially DC. The characters were all created as separate entities in their own worlds, arising from different storytelling genres and styles, and DC's characters initially crossed over only infrequently and tenuously. So when they did finally become more integrated into a common universe, it became quite a hodgepodge of mismatched styles -- sci-fi, fantasy, myth, realism, etc.
I think maybe I know how this movie will go, I have already seen Frank Miller's comicbook story Batman v Superman from a friend who collects and know of Hulk-ing characters like Doomsday in Saturday morning toons.
Miller never wrote a story of that title. Maybe you're thinking of
The Dark Knight Returns, which is a clear influence on this movie, but it's just as clear that the movie is far from being a direct adaptation of it.
I wonder if DC would have been wiser to do a stand-alone Wonder Woman movie....you have characters like Tomb Raider and tv like Agent Carter, would a Wonder Woman in a stand alone movie have not worked better?
There is already a standalone
Wonder Woman movie in production for a June 2017 release. It's been filming since last month. It'll be the next DC film after
Suicide Squad and before
Justice League Part I. Chris Pine is playing Steve Trevor.
Well Iron Man 3 happened in December around Christmas time. Tony Stark's house was blown up, Airforce One was blown up and the President was kidnapped by terrorists. And we saw neither hide nor hair of SHIELD or the other Earth bound Avengers.
I think the idea is that events unfolded too quickly, and Tony was largely cut off from his normal lines of communication and thus wasn't in a position to call for help.
Thor TDW happened mostly on Asgard, but the final fight happened in London, in the afternoon. No Avengers showing up is ok. They wouldn't have the time to assemble.
And we did see SHIELD dealing with the cleanup in the following week's
Agents of SHIELD episode.
Captain America and Black Widow uncovered HYDRA was inbedded in SHIELD and planned to commit an act of mass murder using 3 arc reactor propulsion systems. The event appears to happen in the Spring. Hawkeye is a member of SHIELD and we don't see him. Stark works closely with SHIELD and helped design the new hellicarriers, and he doesn't get a call.
Stark was briefly seen as one of the targets of Project Insight, I think. But in the wake of IM3, he seemed to have gone into retirement from superheroing; at the very least, he needed time to recover from the surgery that removed the arc reactor and fixed his heart. (I wish AoU had given some explanation for why he came out of retirement; my personal view is that it was in response to the unearthing of Hydra.) As for Hawkeye, maybe he was at home with his wife and family.
Banner and Thor are around, but no one contacts them either.
Thor was back on Earth, but we don't know if he let people know that. He seemed to be content to focus on being with Jane. As for Banner, maybe he's not someone you'd call in except as an absolute last resort. Would you really call the Hulk if you needed someone to swap out a microcircuit in a firing computer? Banner, sure, but given that he'd surely be facing resistance, he wouldn't stay Banner long enough to do the job.
Also, of course, there's the fact that SHIELD was being run by Hydra agents at that point, and Fury, Hill, Cap, and Widow were out in the cold. As with Tony in IM3, they didn't have access to their normal lines of communication. They had to make do with what resources and associates they could get their hands on.
Not to mention that, prior to TWS, the Avengers were still a SHIELD-run operation, and SHIELD was under Hydra control. It's possible that Pierce and his agents were working clandestinely to keep the Avengers from coming together as an effective force.
