If episode four can be remembered for one thing, it's the coming out party for Allison Brie's Annie.
From the nose to nose confrontation with Senior Chang in the cold open for her "hurtful, racist" evaluation,s to her making nice to Abed for making him wait 26 hours ("I was livid.") by buying him the three (good) Indiana Jones movies, to everything she did in between, Allison Brie just ruled this episode. She's an 8, which is an English 10.
Although I think Troy had the best line: "Do they experiment in the butt? Do you get paid more if they experiment in the butt?"
Pairing off the characters in odd couples and seeing what happens is working. Looking forward to when Annie and Pierce get an episode together.
IIRC, Duvall wanted the same money Pacino got, and was told to take a hike. He figured the movie wouldn't be any good without him, and was wrong. Sure, the movie would have been better with him, but it was more than just OK - I'd say even good as it is....
