Remember blockbusters? The closest anyone will get to that blockbuster feeling in Fall 2020 is the second season of Disney+’s flagship series, “The Mandalorian,” which dropped its premiere this morning, a little less than a year after the show debuted with the streaming service in November 2019. When the action of “Chapter 9: The Marshal” hits its climax, and the aspect ratio has to expand to fit it all in, it’s hard not to think a little bit about what was lost in a year without Marvel, Star Wars, or other blockbusters. Luckily, the season premiere of one of television’s most beloved current shows isn’t pure spectacle, finding ways to honor the deep Western genre foundation of season one while also dropping hints of where this year will go.
