Todd Spangler NY Digital Editor Netflix says its ad-supported plan includes “the vast majority” of TV shows and movies available on the standard no-ads tiers — but more than a year after the streamer introduced the cheaper option, several popular titles remain unavailable to customers with the ad plan. Most recently, Netflix customers noticed that Eli Roth’s horror film “Thanksgiving” (pictured above), added Feb. 17 for subscribers on ad-free tiers, is unavailable on the ad plan.
