I've been preaching the gospel of Heroes ever since the 4th episode when future Hiro showed up and rocked my world. The first episode back from the break didn't impress, but last weeks raised the bar again. I think that changing the cast lineup for season 2 is the best idea ever. It means that they can kill off characters with extreme prejudice! Always good! Even Galactica suffers from the dreaded "keep the main cast" status quo, ie. Starbuck.
