Enjoying a boost of attention (and comments from indieWIRE readers) today is John Pierson's open letter to Michael Moore. The film opened nationally on nearly 450 screens with about $4.5 million at the box office. Thats a decent number, but below industry predictions...

UPDATE: For those keeping track, I just learned that "Sicko" will expand from 441 to 626 theaters tomorrow (Tuesday) and the film will be on 700 screens this Friday (July, 6th).
