That is very impressive. Obviously the PNF (Pilot Not Flying) in this case was the F/O, doing the filming.
A curved approach like that is only possible since GPS became an approved navigational aid for aviation. Previously only straight-in was achievable, flying down an ILS path. You can be assured there is a lot of cross-referencing going on in a procedure like that among terrain like that. The touch-down was perfect- you will see the jerking in the camera if it's otherwise- it's magnified at the sharp end of the plane.
That is an especially low ceiling, too- I'd estimate 300 feet. That's low for a GPS approach. They would have a ground-based GPS augmentation system to fly to those minima.
One of the greatest thrills in aviation is to pop out of the murk close to and lined up on the runway after flying for sometimes hours in cloud. It's like magic!
