I got hooked with the first series which was gripping, interesting, provocative, etc. As the season continued things got more and more preposterous and unbelievable, but, okay, I went along with it... Drama, SciFi, Action, etc. Then came the second season. It started out okay (you know, willing suspension of disbelief and all that) but as the season continued the writing gradually became some of the most trite, banal, and "Terrence this is stupid stuff". Good guys becoming bad guys, becoming good guys, becoming bad guys, becoming good guys. Total confusion among characters and the Harriet Traymore character, while I suppose is channeling Sarah Palin, is the most obnoxious character I've seen on TV in years and her Southern accent (why are Southerners always depicted as idiots?) has to be the worst ever. The only possible defense for this obnoxious writing/directing is that the whole thing is intended to be camp. Didn't work for me.
