Today on TV

Survivor: Fiji (7 p.m., Ch. 2): One of the best reality shows on TV begins its 14th season with a couple of twists. First, all of the castaways are in the same tribe when they arrive on the island — they won't be divided into two groups until the third day. And, second, one tribe will be living a (relatively) luxurious life while the other has to scratch out a meager existence. Oh, and this time there is not one but TWO hidden immunity idols! Gasp! On a more serious note, after enduring all sorts of unwarranted criticism for temporarily dividing its cast along racial lines last fall, "Survivor" comes back with another incredibly diverse group of contestants this time — 13 of the 19 castaways are African-American, Asian-American or Hispanic.
