On the frosty morning of Dec. 9, 1921, in Dayton, Ohio, researchers at a General Motors lab poured a new fuel blend into one of their test engines. Immediately, the engine began running more quietly and putting out more power.

And on.

Fortunately, while there were indeed some hiccups, we still had plenty of fantastic television on hand to take our minds off the grim daily reality, ranging from established franchises and quirky newcomers to imaginative adaptations and several foreign offerings that proved to be surprise breakout hits. With apologies to the many great series we just didn't have room for on this year's list, here are our favorite TV watches and binges for 2021, in no particular order:
