Batman: The Killing Joke (2016)
Based on the graphic novel by Alan Moore (purveyor of some very adult-oriented comic strips), this sees Batman in a showdown with a truly chilling incarnation of the Joker, and was the first Batman film to get an adults only rating in the US. It’s scary and disturbing, and about a million miles away from the “kapow!” Adam West TV series of the Sixties.
