In fact as you mention this there are many that were not appreciated at the time by the social condition as a step with citizen Kane in 1941 and the marketing of the same cinema as there were cases that were overshadowed by the top box office given the case in Cadena Perpetua in 1994 that was erased by Forrest Gum and Blade runner in 1982 because that same month they released Star Trek II: The Wrath of Khan, Mad Max 2: The Warrior of the Road and TRON. Probably too much science fiction for an overflowing public. Maybe if in that time they had approved the cannabis as now they would not need the 3d glasses and they would not criticize them so hard hahaha
