Fantasy and science fiction are highly “adaptable” genres. Stories can be haunted houses in space (Alien, Event Horizon), westerns (Outland, Looper), even romances (The Time Traveler’s Wife, About Time). And they can be about cops and robbers—and aliens and werewolves and whatever the case may be. So in these future and retrofuture worlds... How do we lay down the law? Is Pre-Crime legal, is “retiring” Replicants just state-sanctioned murder, are Jim Butcher and Anita Blake detectives or vigilantes? Join “Our Gang” for Law & Order: Sci-fi and Fantasy Unit. Also we take a look at what we think is the underappreciated DC film, Shazam.
