They are not bugs but features. The problem they have is that their catalog is mostly filler content at this point. If they addressed the "bugs" you'd be looking at a fairly sparsely populated page with mostly stuff you've already seen.

Netflix is designed to suggest that they have more content than they actually have and that the reason you haven't found anything worth watching just yet isn't that they don't have it but that it's behind the next page of filler content. That's why they have the horizontal scrolling and the endless generic groups of the same content that you've already seen. It's all circular. It doesn't matter how you navigate, it's always the same stuff that surfaces.

I cancelled my subscription last year. I'm planning to re-enable it in one month bursts only if/when I know they have something new I actually would like to see. I'm not paying anyone to watch ads.
