Based on a book series, and adapted by Fred Dekker and director Shane Black, the pilot is crazily violent, but also weighted down by clunky dialogue. Ryan Kwanten is part of the gang that gives Hedges ample reason to want them dead, with Yvonne Strahovski as the proverbial hooker with a heart of gold. There still might be a decent show here – and as a western fan, it would be nice if there were – but initially, “Edge” has a few too many duds in its chamber.
