Since the pandemic migrated pretty much all movie-viewing online, several streaming sites have responded with new levels of ambitious programming. Among the most conspicuous is the Criterion Channel (I’ve written recently about some of their most welcome offerings, including “Compensation” and “When Tomorrow Comes”), but the site mubi (which is available as an Amazon channel) is doing remarkable work a bit more under the radar. This week, for instance, it brought out “About Some Meaningless Events,” a nearly lost masterwork of Moroccan political cinema which for decades had been entirely unavailable. mubi’s selections cull some of the best in recently released movies as well as hard-to-find classics, both American and international, including some unduly obscure masterpieces that I’ve been enthusing about for decades to anyone within earshot. Here are ten of them.
