Ok -- I know-- Hype and all that-- I hate to hype something-- but Heroes is FREAK'N AWSOME!!
SO... I ask that if you haven't seen it-- give it a chance. Watch a couple episodes. Best of all -- Watch 1-4 and then decide "Do i want to stop watching this show or do I want to continue following this?" Some people may be able to say "I don't think I can stop watching this now."
Now almost every character is amazing. Some more than others. Though almost everyone can agree that the character Hiro, is amazing. So amazing I looked into his actor and discovered that not only is he a geek like many of us...
"he's a Brown University graduate with degrees in mathematics and computer science with a theatre arts minor, at one time he worked for Industrial Light & Magic in special effects, and has had a background in comedy as well as drama."
He's what many nerds/geeks/etc wished they could be. For those who dont know - Industrial Light & Magic is one of the biggest special effects and lighting companies in the world. Having worked on almost every single big hit movie/show in some way at some point. It was started by George Lucas and has a list of movies that goes back over 20 years.
And then -- just watch the show ^_^
