I don't know what were the wind and weather conditions at the time. If this was a calm sunny day, then it is not as impressive compared to the docking manoeuvers that spacecraft have been doing for decades.
People forget that the issue is not weight but inertia. Objects have the same inertia in space despite being 'weightless' and the space docking manoeuvers are pretty damn impressive in their own right.
The additional complications that the lander will have to face on Earth include atmospheric issues like high winds and other weather phenomena. That will be the impressive part when it lands during high cross winds.
