13 Reasons Why is Netflix's newest hit -- but also maybe its most controversial ever.
What do YOU think of 13 Reasons Why??
Wow, what a fabulous way to open the Grammys!
Rock legends AC/DC delivered a killer performance of Highway to Hell and Rock or Bust.
Considering the group has been around since 1973, we're seriously impressed by their energy and rock 'n' roll prowess!
We especially loved how the crowd let loose to the band's jams, like Paul McCartney!
So, do YOU think AC/DC should have opened the big event?
