East of Eden's commanding market position stems from its October 1 Netflix premiere as a seven-episode limited series starring Florence Pugh as Cathy Ames in Zoe Kazan's Steinbeck adaptation. Strong critical reception, including an 87% Rotten Tomatoes score, combined with the full-season drop and Pugh's star power, propelled it to the global English-language top spot in its debut week and sustained #2 worldwide viewership into mid-October. Recent Netflix charts show it trailing only newer arrivals like Below while outpacing holdovers such as Monster: The Lizzie Borden Story. An upset would require a surprise late-week surge from an untracked title or accelerated drop-off, though the series' established momentum and lack of major competing premieres this week make that unlikely.
