In what regard are you not blown away? Taking good landscape shots is a real skill.
yes, good landscape photography is incredibly difficult.
Not to detract anything from the professional portrait and event togs but it is much easier for a beginner to pick up a camera and get reasonable photos of people once they have mastered the basic technical side. The same is not true about landscape- engaging landscape photography involves creating interesting compositions under excellent lighting. Pointing your camera at a lake/forest/mountain and taking a snap doesn't work, snapping away at people having fun at an event tends to produce at least acceptable results. Excellent portraiture is an entirely different question.
Try to find captivating scenes and go back to those locations at different times of the day and the year. Some landscape work better in winter/spring/summer/fall. Summer is often a difficult time because the sun is strong, the air is hazy and distorted and on a fine day the sky can be dull. Sunset and sunrise are generally the best times, especially sunrise because the sky is clearer, but this all depends upon the angle of the scene WRT to sunlight. And sunrise doesn't mean early morning, it mean getting into position in the dark and waiting for the first sun rays to make an appearance.
Other than that concentrate on compositions. Look to find balance (shapes, colours or contrast), to have a perspective showing foreground, mid-ground and background interest and ideally paths that connect all elements. Move around th location to find different spots, sometimes walking 50ft one way will suddenly open up a much more intriguing vista, e.g. instead of a view across a river to a mountain you end up with a view down the river leading to the mountain which directs the viewers eyes form foreground to background.
Doing things like that should see you getting acceptable landscape results. Going form acceptable to excellent I have no idea because I am still failing to do that myself.
