I don't think "Heroes" is just a great show,nor "Lost". The best thing they have is "Concept" but they both have too many problems.
In any case i'll be waiting for "Heroes",especially since - Kristen Bell joined the cast,and Kristen is one of my most favourites Actresses.She did such a great job in "Veronica Mars"(VM). To be honest Kristen Bell and Tina Majorino were the 2 main reasons i kept on watching "VM",'till the CW network cancelled it.
If Kristen Bell were 5 years older(or even 3) i would suggest her nomination for the part of Sammy-Jo in Deborah Pratt's possible QL movie.
