Heroes is a lot of fun, one of the two series that I can be bothered watching (the other is The Dresden Files).
Of course, they just revealed both Eric Roberts and Malcolm McDowell on staff. I'm sorry guys, but I realy don't think this is going to turn out well for anyone. Eric was over the top and a major reason why the recent Dr Who film was such a stinker. And McDowell, whether you see him in Star Trek Generations or Tank Girl is just the same over the top villain.
If you HAD to cast them, why not break with tradition and cast them as the good guys?
