[Semaphor]

For me, the reason was partially the engine, partially their active work at confusing me.

I would keep seeing stuff I don’t want to watch, and they would keep switching out thumbnails to trick me into thinking it’s something I haven’t encountered. Both of those combined made browsing a chore, and I simply had no interest in using something that’s actively working against me (which is also the reason I went from being an active FB user to only using it for groups and messaging, so it’s not as if "actively working against me" is a Netflix exclusive)

A more minor reason is the lack of information displayed, but I could have handled that.
