Morgan Spurlock is back, and he’s going after fast food again. It’s 15 years since “Super Size Me” made him a star. Now “SS2: Holy Chicken” goes after the poultry world — the chickens that come through Drive Thru windows. I always worry about the Nuggets, and I guess now we’ll know why. “SS2” isn’t going to festivals, oddly. It’s just opening on September 6th in NY and LA from Samuel Goldwyn.
