the 2 'low hanging fruit' solutions they can implement to drastically improve the recommendations:

1. use the 'percentage of series viewed' as a weight for the recommendations, so i don't end up with a list of shows similar to the one i watched only for 1 episode

2. filter out the shows/movies i've watched already

i can't even imagine why these haven't already been implemented, seem like such a no brainer.

These posts depress me. They are always showing off some cool algorithm that is oh so clever, and yet Netflix recommendations are just the same films over and over again. Amazon instant somehow nailed it - I keep finding new shows/films that are actually well aligned with my viewing history and rating. Maybe their offerings are more tailored to my tastes? As a tangent, I've been meaning to start a discussion on how u…

The core issue for me is that of the dozen or so shows and movies I would be interested in watching, on average 0.5 are available via netflix. So I spend a lot of time searching in futility for that show or movie I half remember wanting to see. During that search netflix is trying to recommend a bunch of other things to me and I find it annoying and distracting.

Also, could somebody somehow post a schedule of show/movie availability? Shows get added or removed on a regular basis and I always find out by accident.

(e.g. "Oxryly1! We do NOT have 'Guardians of the Galaxy' at the moment. We expect to add it in 4 months time. Thank you.")

indeed.

You do realize this post was not about recommendations, right?

After using Netflix for quite some time, I have no evidence to support any hypothesis other than that their overall selection is secretly horrible and that they wish to conceal this however possible.

Evidence includes but is not limited to: Their user interface appears to intentionally border on unusable, a rambling Quora post by a C-level exec about how advanced search (a la Gmail) would ruin the world, and they've shut down their API, making it harder for third-party sites to index their selection, and allow positive UX to be possible thereby.

I wish they would note which movies they've shown to me and I've chosen not to watch 1 bazillion times. Then stop showing them to me. For recommendations, isn't knowing what I chose not to watch as important as knowing what I've actually watched?

Yes, they should - this is a well-understood use case in recommender systems.

Surprisingly disappointed by this feature. "...Netflix records how much was watched and where the viewer left off." Isn't that kind of obvious?

I also wish there was a reset button for this. Sometimes I skim through a few seasons / episodes and when I go back and rewatch it there will be 3-4 episodes per season already watched and it will ask me if I want to resume, when in fact I don't remember.

So there's 2 billion hours watched per month, but a few billion "view" events per day? So let's round and say 100B view events a month, so 50 events per hour viewed? I wonder if this is because people preview a ton of stuff they don't watch, or are they recording pauses, or ... ?

good point, not sure. maybe it is from people hitting play once and binge watching a series consecutively "your program will start in 3...2...1..."

They also bizarrely consider something that you have only watched a few seconds of (by accident) as watched and like to show recommendations by that. Through human eyes, Netflix's recommendations are especially dumb for the reasons you and I give. Equally pointless is recommending things I have already watched in a genre instead of other items in that genre, and doing a filter bubble where they keep narrowing down to…

My favorite example of these "dumb" (to human eyes) recommendations happened to me a year ago: https://twitter.com/chimeracoder/status/423877639666167808. Note the reason Netflix recommended it.

I have no trouble understanding why a recommendation engine might yield this sort of result (e.g. parents sharing accounts with kids), but I'm a bit surprised that Netflix doesn't do a better job of inferring when different people are using the same account, even when the users don't keep their profiles separate explicitly.

The amusing part is that I've never even seen the show myself. My friend happened to watch a single episode of Law & Order: SVU on my computer while she was staying at my place... and now I'm probably on a government list somewhere after this recommendation!

There is. Click on Recently Watched, find the show of interest, click on the X to remove, and tell it you want to remove the whole series.
