I'm very impressed with the ZERO death/major injury count, but it's not superhuman. Aircraft are designed with the possibility of, shall we say, less-recommended landing strips. It's a bit harder to get the plane ready for its next takeoff, to be sure, but they're designed to promote passenger survival. Also, pilots are (or at least should be) trained to cope with a variety of less-than-ideal circumstances; and the smoothness with which the plane was put down is really a consequence of that. You can't really do anything else - if you're going to put a huge craft down on water without killing everyone, you're going to have to do it fairly smoothly. All the same, hats off to the crew (not just the pilot) for handling it well. As emergency landings go, that was pretty well executed.
