Abrams said he didn't want CGI sets. So he got his wish.
But he did have sets that used CGI nonetheless. Remember those interior shots of the Narada that had bottomless pits and very open areas? Why not make a partially built engineering set with CGI enhancements? Put in as many real elements to give the actors stuff to interact with and enough real set to give the general look to have the CGI extended onto. Kind of like they did with those stupid water tubes.
I think it's silly and narrow minded to simply dismiss the CGI aspects just because it's CGI, especially when a massive bulk of the film relies heavily on it.
