It's no coincidence. People who watch Lost don't want to watch another show full of mysteries and myths to decode. They want to unwind and think about what the fuck just happened on Lost. I don't give a crap about reptilian aliens after watching Ricardus being told that he has to kill the man in black. (Line of the night, by the way: "She said your English is awesome.")
Add to that the fact that V went on a four month hiatus and has a new show runner installed at the helm (Chuck's Scott Rosenbaum) and things don't look good for Elizabeth Mitchell and company. I'll check it out because I like Scott Rosenbaum and want to see what he's gonna bring to the show, but it doesn't look good.
At least V is better than FlashForward.
