People are talking about shaders, realism and how necessary it all is - what about the game itself? For you it seems to be less important, as you never mention this aspect.

Graphics should support a good gameplay, not cover crap.
For me, good gameplay is essential. Then Graphics come - afterwards, not before.

Apart from that: Who said everybody wants realism? You can have realism every day - just try to open the door of your house.
Where have all those unrealistic but gameplay wise excellent games gone? I don't want graphic demos, I want fun while playing.
