This might not be exactly what you are asking, but the company that used to know me better than I knew myself was Netflix. I have fairly eclectic tastes in film, with my favorites ranging from early 20th century European silent films to anime to actions films. If you ever run across a Sergei Eisenstein film animated by Studio Ghibli that stars Jason Statham, please let me know. Up until about 6-8 months ago, Netflix was able to suggest films to me that I was either unfamiliar with or had not considered watching, and if their magic algorithms rated it 4-stars for me, it was a sure bet. They were able to discern my tastes so well that I started watching things that didn’t look at all interesting to me because Netflix said I would like it, and 99% of the time damned if I didn’t. Those were the days.
Unfortunately, something has changed and those halcyon days of Netflix yore are a fading memory. Now it seems that because I gave Elfen Lied 4-stars, Netflix thinks I would give Veggie Tales 5-stars. It’s unfortunate to see a company that has figured out the “secret sauce” decide to add something new to the mix, with the result being nothing more than thousand island dressing.
