Heroes was a real treat for me. I started the first season as the show was partway through airing its second season, and by the time the second season was halted due to the writers' strike, I had caught up. When I got toward the end of the first season, I was watching several episodes a day. It's THAT good. I just couldn't stop watching.
Heroes begins with the introduction of several people around the world who are discovering that they all have special abilities. The major characters include Peter Petrelli, who thinks he can fly, his aspiring Senator brother Nathan, Hiro Nakamura, a Japanese cubicle worker who can bend time and space, Niki Sanders, a single mother whose split-personality alter ego has strange consequnces, and Claire Bennet, a Texas cheerleader who can heal herself under any circumstances and whose adoptive father is engaged in strange affairs.
It's all held together by a brilliantly apocalyptic plot and a villain who brings up some very interesting questions about evil.
All of the technical aspects of this show are spot-on. If you like good television, this show is for you.
