what is she thinking?

I tend to enjoy Stephanie Zacharek's film reviews in Salon, but lately I've been wondering what the hell happened to her taste. She poopoohed The Dark Knight (one of only 3 top critics on Rotten Tomatoes to do that), WALL-E, and, last year, both No Country for Old Men and There Will Be Blood, and yet gave her blessings to Meet Dave, Drillbit Taylor, and You Don't Mess with the Zohan. Huh?
