The great science fiction writer Harlan Ellison recently passed away on June 27. Whether or not one is familiar with his large body of work (the majority of which are short stories), “A Boy and His Dog” (1975), is definitely worth watching. It’s the first and best feature film adaptation of one of Ellison’s stories and features Don Johnson as Vic who, with his dog Blood, struggles to survive the post-apocalyptic wasteland that the southwestern U.S. has become in 2024.
