Maybe i wasn't clear in my statement - will they, for AM show a whole civilization down there, in caverns, where a world exists, hidden by water or will it literally be like, for want of a better example, sponge bob's bikini bottom!
I get 75% has yet to be explored, but people are far more likely to accept a planet, out there in space than a world at the bottom of the ocean (in my opinion).
Or, would they go the route that there was once a great civilization down there, but was wiped away, with only a few surving and the blood line/genetics got passed down and eventually reignited in Arthur Curry.
2ndly, in todays society, an island suddenly becomes visible that holds mysteries beyond we can ever imagine, how are they going to handle that?
So to conclude, i just can't see how or the WAY they are going to interpret this - to please the general audience, which, may not be as forgiving as us fan boys.
Also, i guess this stems back to my disappointment from MOS - the human race witnessed first contact, with ET life and we didn't see how this effected the world, a few days later they are all back at work and everything seems normal.
Like many posters have said and i agree, it would have been awesome if in MOS, when Lois was trying to track down this mystery man, that along the way she heard stories of other mystery men/women. She may have heard of a man, pulling out fishermen from a sunken boat - when she investigated - it wasn't 'her' mystery man etc - at least that way it gives a nod that this world has super human like people.
I really hope BVS answers these questions.
