Don't know if y'all have been living under a rock, but SNL got pressured into hiring a black chick.
I don't like the way she was just randomly tagged on in the middle of the season by herself. Seems very artificial and forced. Also, to show how progressive they are, she got more screen time in her first episode than some of the other featured players have, combined, all year. Remember, they typically ease featured players in very slowly. They rarely get more than a few throwaway straight-man lines per episode.
Anyway, all that said, I can tell from her performance this week that she'll be funny and I think she'll be a nice addition and an asset to the show.
