This version is still imperfect, there is severe class warfare and a history of british-like colonialism.
Well, that's my point, we can already see examples of that from Earth history, making Krypton DIFFERENTLY screwed up (AFAIK, Earth has never had a viable culture which distanced itself from emotions like that) made it truly alien. As it is, we're getting something more akin to a standard Trek alien-society-that's-a-reflection-of-our-own of the week.
The 'emotion is dead' angle doesn't work for me, leave that to Brainiac and Colu, they had been using that since the 60's it wasn't original.
IIRC, not really. Coluan's WERE emotional, that's why the Computer Tyrants took over from them and they fought to be free. Silver Age B5 was emotional as all get out, screwed up, but emotional. Colu as coldly logical IIRC only goes back as far as the Zero Hour reboot. B2 was a basket case in his own right.
Krypton in the silver age seemed like a cautionary tale for humanity and kal was the messenger to show them what their own arrogance and warfare could do.
Silver Age Krypton was pretty close to a perfect society. There was no hunger, no deprivation, no class struggle or racial prejudice, and the only problems came from a criminal element who were usually chucked into the ultimate oubliette, the Phantom Zone, exiled into a position where they could do no harm.
Only the contrived "No no, we mustn't listen to our own acknowledged most brilliant scientist, despite being a world based on the wonderfulness of science" can be seen as a real flaw and that has never quite worked as an argument to me (My six year old mind on reading Superman comics was just plain ANNOYED at the stupid Kryptonians)
