The navigation and interface are quite strange.

That's odd, because in my opinion, it's very minimalist and user-friendly. The navigation is simple: you either type in the search bar or open the alphabetical list; nothing extraordinary. The only thing that might be annoying is the drop-down menu with blocks of 5-10 titles, each with sub-, dub-, season-related additions.

There's a lot of advertising, and it complains about ad blockers.

I haven't seen a single ad, nor have I encountered any complaints from the website. I use Firefox with AdBlock Plus and NoScript (and I didn't even have to allow anything except the main website, which is rare for 2018).

Also, the latest episode with subtitles isn't available, so I had to watch it dubbed.

I checked just to be sure, and it's all there. Perhaps you visited a malicious imposter website that's filled with miners, banners, and viruses?
