2015 TRIBECA FILM FESTIVAL: NBC's "Saturday Night Live" has become an institution of American television. One line that rings profoundly true in Bao Nguyen's thoroughly entertaining documentary "Live from New York. about the institution of 30 Rock Plaza, is that people don't speak about what "SNL" means to comedy. Many of us have grown up with it in different ways. For me, it wasn't the 90's that had Molly Shannon and it wasn't the 00's that had Will Ferrell and Tina Fey. Discovering some of their more iconic characters and importance in my later years, I was first formally introduced to SNL just under a decade ago. That's with consistent watching and growing to love a die-hard cast that included Kristen Wiig, Bill Hader, Fred Armisen, Andy Samberg, and more. It's only now that I go back to the earlier seasons to see people like Cheri Oteri and Horatio Sanz and discovering that their humble beginnings were just in my back yard.
