Hmm, I feel about it what some people feel about 'Sherlock': it's entertaining, but it's not Sherlock Holmes.
Well, Kevin Sorbo's Hercules wasn't really Hercules either. The goal of adaptation is to create something new that builds on the essence of the original, and some adaptations are greater departures than others. What matters, ultimately, is whether they're worthwhile stories in themselves. And that's the part I'm not sold on yet. I found the pilot fairly bland.
