I mean Korea is still a significant market for them because they make huge money off of album sales. I agree that their KR albums have always been filler heavy.
As for dance videos, they're good if the dancing is good, and they're better than many bloated 'story' videos. I dreamt about a Korean BoA dance video for years before I got it with Only One, but on the other hand I've also dreamt of f(x) getting something besides a standard SM box, and a video that matches their unique colors and artful concept style. SuJu's videos have been grey and same-y to the point of parody. Taeyang's Ringa Linga dance video is amazing. It depends. SNSD have def had their fair share of lazy box sets.
