I find the Netflix recommendations largely non-beneficial considering their lack of selection. Most of the movies/series I want to watch are not on Netflix at all.

Moreover - I think the internal algorithm for training their models will be to maximize "continuations" of watching series enabling binge-watching. While this may be a good measure of engagement for THEM, it hardly is for ME. I would much rather that the choice was made out of the global list of "good stuff I should be watching" versus the "list of stuff Netflix sales people could buy and negotiate for".

I do think it's cool that when you type in a title that's NOT in their system - they can recognize it and recommend similar titles - although - it's a very good bet that actually clicking and watching one of those is highly likely going to a waste of time.
