The former YouTube star explores coming of age online in his film 'Eighth Grade.' "This awful D-list celebrity pressure I had experienced onstage has now been democratized," Burnham says.

Elsie Fisher, who plays Kayla in the film, is nominated for a Golden Globe for Best Actress. Also, Kevin Whitehead remembers jazz musicians we lost this year.
