does anybody here know a lot about recommendation algorithms? The one I'm interested in seems obvious to me, but it's never implemented so maybe it doesn't work, or it serves outliers and not the mainstream so why bother. The data is there, but I don't get to mine it. (heheh "mine" it)

I don't want to know what's popular, I want to know what other people who share my past tastes are watching currently. Doesn't matter the size of my niche, why can't i find my niche, and be shown my cohort?

I just don't feel it's an impossible task to find, for example, a set of people who enjoyed Deadpool 1, Guardians of the Galaxy 1, but think the entire rest of the superhero cavalcade is utter garbage. ok, I'll allow Kickass also, and a grudging nod to Iron Man 1. (as an illustration, I just searched to look up the name of Iron Man, I could only remember Tony Stark. Top search results were "a fictional character", "played by R Downey Jr", "Marvel cinematic universe"... You see, none of those is Iron Man 1. I don't care about the horde of people who care about a supposed cinematic universe. We (in my cohort) liked the first one, and what we liked about it wasn't continued in the 2nd.

How about preferences that show I like a few early films with say George Clooney, but after that, no. Julia Roberts, same. I remember when Meryl Streep was a new actress, but now she's a red flag. I'm sure my tastes aren't shared by everybody, but I'm also sure, since I can articulate reasons, there must be others who in general share them, people who are willing to watch what's new and trendy in some way, but then not beat the dead horse. Oh, Spielberg, a few winners, but overall "nope nope nope", the way he aims at sentiment is a zero for me.

I originally had this idea back in the 80's when Consumer Reports had their monthly mail-in bingo card for what current movies you liked, then they would tabulate what was popular among their readers. That type of "best of" list is entirely missing co-variance, which I think is where I live.
