I've been watching Alias for a while, and something came into my brain recently. J.J. Abrams, whatever his flaws, does not milk stuff. Lost and Felicity both came with time stamps on them - both less than seven years. With Alias, he might be accused of milking the show, but I think Lost has proved that he good and learned that lesson.
Trek has a history of being milked, stretching clear back to the days of Gene Roddenberry. It's nice to think that this time, maybe that won't happen.
