Quick review of the two-and-a-half-hour finale of Lost: I liked it. It worked. Others will probably be frustrated that some of the mysteries of the island--like the origin of the ancient man-made structures--were never fully explained. Not me. I thought the characters reached closure. And this last installment of the show had plenty of great moments for the castaways and no shortage of good drama. Revealing too much about the island's workings would be like George Lucas introducing midi-chlorians as an explanation of The Force in the Star Wars prequels: an unnecessary effort to connect dots that didn't need to be connected.
