After they hit a home run last week, South Park fouls out in this episode. Instead of political or social or religious satire, it turns into one long-running joke about Cartman acting like a greased pig to avoid his immunization shots. Cartman running around on all fours and squealing like a pig is funny the first time, but not the second, third, or fourth time. The other main cast of characters is virtually ignored, and the plot with Randy was dull and devoid of laughs.
South Park could have made more points about the absurdity of anti-immunization hysteria, but they chose not to for some reason and just try for the cheap laugh.
Very disappointing coming on the heels of the spectacular season premier.
