Which show do you think handled it best? The 4400 had the best premise and the 1st season was great Heroes the first season was just very new. Went down hill quickly No Ordinary Family - was better than I expected but took too long to hit is stride and got Cancelled Alphas - it is not really gripping me yet . . but i'll See Rocket River
I watched 4400 and Heroes, and I probably liked the first season of Heroes a little more. But yeah, anything after season 1 of Heroes was awful, and 4400 got too muddled as it progressed.
Try the UK series Misfits .... the characters are unlikeable but the story is hilarious ... plus there are bewbies shown sometime!
