Saw the pilot earlier--it was very good, somewhat like Minority Report and Eagle Eye meets The Equalizer, except that there are less gadgets and the "clients" have no idea they're being watched.
Ben Linus can do no wrong every time he's onscreen, heh. Jesus maybe needs to put on a disguise (his homeless person look, perhaps) every time he walks on the street carrying a huge gun, as pretty soon everyone will recognize him. But I liked the fact that he avoided killing just anyone with his shots, which were mostly leg and knee shots, and only targeted the ones who deserved it.
Nolan and Abrams delivered in the pilot, effectively setting up the premise--consider me hooked.
