I concur, if I have to limit myself at the images displayed on that page, the algorithm seems pretty terrible, to be honest. I like a sharp image, but judging from these images one is supposed to watch a Minecraft game, not a movie.
Edit: pictures here are better, though

Aliasing is still there, but at least I can see a reason for taking it into consideration. They really ought to change the pics in the homepage.
Edit 2: these
https://graphics.ethz.ch/~cengizo/Fi...udyImages.html are even better. Interesting...
