I feel like they've either got to go outside the show for an established comedian with a clear point of view, a la Amy Poehler, or give it to a relative unknown from within who has the smarts and the chops.
Some of you know that I work at a place called Geek Bar in Chicago. We actually had a candlelight vigil all weekend in honor of Nimoy. It was really quite wonderful to see people come in, watch some Trek, share some memories, and have intensely personal moments while lighting a candle. He certainly deserves that level of respect.
I've been hate-watching this for the last season plus, but I really liked that episode. It makes me hopeful (perhaps wrongfully) that there will be an overall shift in returning to what made the first couple of seasons good.
