I think some are missing how technically difficult it is to pull off a shot like this - particularly if these people were just tasing through. Trying to balance exposure, particularly shutter speed, to blur the water, but to be short enough to not have the people completely disappear is a challenge to say the least. I like the attempt. It may have been better a 1/2 stop faster, rendering more of the people.
I like that it isn't just another shot of this location that has been done over and over again. It's one thing to do a shot and try to replicate wheat others have done. It's another thing completely to try to do something new with a common scene. Again way too much technically correct boring content out there. Maybe I've just been around too long. Trust me, I've taken my share of them. But if I see one more aspen grove or deer in the woods. For a landscape to stand out it absolutely has to have amazing lighting. That exist for about 20 minutes a day. So for the rest of the times you need something else to make images stand out and be unique.
Don't take this as I don't respect those who do standard landscape photography. I get that the journey to the photo is more than 1/2 the experience. And why they love their work.
Long winded way to say I understand why the photographer loves this shot. It isn't a clone of another persons shot. And that is what makes it his. I would love to see it printed on metallic paper.
