The dark side of vacation entertainment emerges in "Blackfish" (9 p.m., CNN). Released theatrically in July, this documentary makes its television debut tonight.
A popular destination for decades, SeaWorld in Orlando, Fla., received unwanted publicity in 2010 when
Tilikum, one of the killer whales used in its
spectacles, killed an experienced trainer.
"Blackfish" includes interviews with many former trainers who recall their team's hard work and camaraderie as well as their affection for their captive orcas, creatures with incredible intelligence and obvious emotional range.
Many feel that living in a crowded, dark tank for most of his adult life may have driven Tilikum to psychosis and homicidal rage. And we learn that prior to this well-publicized event, the same orca had been associated with the deaths of two other trainers.
---At the risk of repeating myself, the best way to get your own reality TV show is to have already appeared on one -- or several. Or too many. Chef Rocco DiSpirito hosts "Restau rant Divided" (10 p.m., Food, TV-G). Even by the meager standards of reality television, "Divided" is extraordinarily unoriginal. Every week, Di-
Spirito will help family restaurants on the brink of bankruptcy or closure get their acts together, refocus and reopen with renewed success. Gee, I haven't seen that before.
For the record, DiSpirito's reality show "The Restau rant" first aired on NBC in 2003. He's been with us, doing pretty much the same thing, for 10 years.
