Thursday's premiere of Survivor: Panama  Exile Island drew a tribal council of 19.3 million a 900,000-head improvement over Guatemala's debut and enough to best ABC juggernaut Dancing with the Stars, which averaged 17.8 mil in the 8 o'clock hour (but 18.7 mil overall). ABC's Crumbs, meanwhile, hit a series low, losing a full half of Dancing's audience at 9:30 pm/ET. Also of note: Smallville, with 5.55 million viewers, saw a half-million fly off from last week's well-hyped 100th episode, and ER's James Woods-guesting eppy drew a respectable 13.8 mil.
