Exactly, I'd love for the DCEU to embrace magic. SS laid the groundwork so the audience won't have much trouble with the concept.
I really want Superman to find the bottled city of Kandor and face Braniac in a future movie.
Huh, that Argus site looks pretty cool. Hopefully they do add meta-human files over time, I want to see more metas than just the JL.
As for languages, the Amazons probably speak an ancient Greek dialect if anything and there might be some ancient Greek influence for the Atlanteans. Considering how much work went into designing Krypton, I have no doubt that all the supernatural civilizations and aliens worlds have their own languages and cultures, but we probably won't see too much of it in JL.
Apparently, the original idea for the Krypton prologue in MoS was to have all the lines in Kryptonian. It's kind of a shame that never went through, even though it might have been too much for GA.
