I've been watching these episodes over and over, while recovering from a cold. Watch her closely. She's the "straight" character, and she makes the whole show smarter, but while she doesn't get top deliver a lot of the jokes, she's great at the comic reaction shots. Her body language when she's listening to Pierce tell a bad joke is incredibly expressive. And I loved her in her squirrel costume, never putting down that giant acorn once. It's never laugh out-loud funny, but great comedy is sometimes more understated than that.We all seem to agree that Annie has been coming on strong in recent episodes, and that's great, but there's no character and no actor in this ensemble who isn't beautifully written and beautifully played, And Britta is more important to the structure of the show than some people are giving her credit for.
