Kinda bummed to hear about the lack of wire work. I know it was to be expected, this being a Zack Snyder film, but I was still hoping to see a return of those graceful takeoffs and landings that we saw in the Reeve movies.
There was something so simple and truly magical about seeing a guy actually hanging in the air, that no CG effect has ever been able to duplicate. In fact, after all these years, it's still easily my favorite special effect in any superhero movie-- just Reeve on some freakin wires.
While I'm of the opinion that -- with care -- CGI can do anything and look good doing it, I do seem to recall being amazed by some of the wire work done in the later Superman films. As Reeve got practice in the harness, his take offs and landings became graceful, as you said. Even breathtaking.
Of course, it's been a very long time since I've seen those films. Maybe the fog of years has been generous.
