Saturday Night Live can be funny. It can be important. It can be anarchic. It can be a cultural mirror and a bullshit barometer, irreverent, skeptical, and silly. But when it?s at its best, it is emotional. Triumphant even. Without a doubt, that?s what SNL was this Saturday night, welcoming former star Tracy Morgan back to its stage a little more than a year after a tragic car accident that left him in a coma, with a traumatic brain injury, and fighting for his life.
