EX LIBRIS (2017) on Kanopy. The theatrical release of the documentary filmmaker Frederick Wiseman’s latest movie, “Monrovia, Indiana,” may have some searching for an introduction or a reintroduction to this director’s large body of work. A good place to start is his previous film, “Ex Libris,” which focuses on the inner workings of the New York Public Library. The movie is delivered with Wiseman’s signature patient observation, which, Manohla Dargis wrote in her review for The Times, “gathers details ranging from the prosaic to the peculiar” to create an “evolving mosaiclike picture.” Like all other titles on the streaming service Kanopy, the film can be viewed free. All you need is a library card.

BAD SAMARITAN (2018) on Amazon. This horror film focuses on Sean (Robert Sheehan), a young thief who breaks into the home of an ultra-wealthy man (David Tennant) and, by doing so, discovers that the man is a serial killer. What happens next feels “a bit like a tribute to the cheesy deluxe-house-of-guilty-mirrors thrillers of the ’80s and ’90s,” Glenn Kenny wrote in his review for The Times. He didn’t think the movie was great, but he did write that Tennant “just goes utterly bananas here.”
