It's a dark pattern and what led me to unsubscribe. See also: getting rid of the five star rating system (I realize this wasn't ideal in terms of figuring out what people want but it was invaluable for cataloging your own preferences)
However, the percentage rating alternative seems to tell me nothing other than a movie I haven't watched yet is a similar genre to movies I have?
Then there are the 'New' movies which don't have any rating at all yet.
The 'suggestions' also seem only to suggest stuff I've already decided not to watch.
