Upon finishing the final season of Dexter, I clicked on an episode in the first season to look up something. I jumped to the 18 minute mark and watched about 10 seconds and closed the tab.
Now Netflix asks me every time if I want to continue watching Dexter from where it now thinks I left off in season one even though I spent a whole year watching all of the seasons.
So I have the same concern. If they have a more sophisticated model, it certainly doesn't get reflected in the UI...
And they force 21:9 movies to be played back inside the 16:9 portion of a 21:9 ultrawide monitor, with massive black borders as a result where there should be none.
I'm seriously unimpressed with Netflix as a company, for what they do with all their resources. Sometimes the MVP just isn't good enough.
I hope their version of that signal is better than what they're presenting in the UI. I have a few movies Netflix shows me as not finished, becaue I closed them just as the ending credits started.
