Netflix infamously doesn?t provide data for how many people watched what, with one exception: When they can brag about high numbers that are not verifiable by the press. And last weekend ? again, according to selectively provided information that can?t be proven otherwise ? Murder Mystery, their latest Adam Sandler romp, became their all-time most-watched blockbuster. As per The Hollywood Reporter, Netflix is claiming the comedy was watched by over 30 million households in its first three days.
