I also have Viki, but DramaFever had more selection.
I won’t go to the other “black market” sites. My wife did that once and gave her computer a virus, which then spread to the router and to my computer. Our ISP then shut down our connection because her computer was spreading the virus on the internet. We finally resolved it, partly by throwing away our computers and router and starting from scratch, but the ISP said if it happened again we would be banned permanently. So that’s not a good solution.
I also think the producers of those programs should be paid a fair price rather than the content being ripped off by the black market sites.
I’m just glad I got to watch “Goblin” on DramaFever, since Viki doesn’t have it.
