Stranger Things 2 & Mindhunter among Netflix's big October shows

Appropriately, the second season will take place around Halloween time, and will deal with the aftermath of Eleven's disappearance.

Other new additions this October will include Season 1 of Italian crime drama Suburra, FBI drama Mindhunter, and seasons 1 and 2 of Australian crime show Wanted.
Mindhunter is based on Mind Hunter: Inside FBI’s Elite Serial Crime Unit, the book written by Mark Olshaker and John E. Douglas, a former agent who interviewed such notorious killers as David Berkowitz, Ted Bundy, John Wayne Gacy, Charles Manson, Lynette Fromme, Arthur Bremer, Sara Jane Moore, Edmund Kemper, James Earl Ray, Sirhan Sirhan, Dennis Rader, Richard Speck, Donald Harvey, and Joseph Paul Franklin. If it's a more gritty Criminal Minds you're after, you've come to the right place!
Billed as the "next Gormorrah", Suburra transports us back to 2008 when "a fight over land in a seaside town near Rome spirals into a deadly battle between organised crime, corrupt politicians and the Vatican."
