 Due to their disruptive nature, simultaneous releases have faced mixed reactions from the industry.Advocates have considered them a means of catering to consumer choice and improving the accessibility of film, and critics arguing that they dilute box office revenue by requiring cinemas to compete with premature availability of a film on home video, and are detrimental to the traditional movie-going experience.Most major cinema chains require films to have an exclusive theatrical window of a minimum length (which in some countries is also enforced by law), so films that pursue a simultaneous release or shorter window are typically screened at independent and art house cinemas only.
