On NBC a new series the Cape is slated as a midseason replacement. I watch a couple of the preview video on it's website and looks fairly decent. Unlike Heroes it looks like it fully embraces the conventions of superheroes. I like the backstory as well and the motivation it give the main character. The full series works as good as the preview looks.
Also I recommend No Ordinary Family. Potentially it shares some of Heroes problem in that it ditches comic conventions (i.e. no costumes, etc) in favor of personal drama. But there is a tighter cast of characters that are likeable and well acted. I find it interesting they give the dad all the original powers of Superman (1939).
