Warner Brothers tries to launch yet another superhero franchise with this big-screen vehicle for the green-masked DC Comics crime fighter, who’s been around, in some form or other, since the 1940s. The result is a deadly disappointment, despite Ryan Reynolds’s cocky, muscle-flexing charisma as the daredevil test pilot turned intergalactic peacekeeper and Peter Sargaard’s movie-stealing turn as a nerdy scientist turned psycho monster. Director Martin Campbell did right by the James Bond franchise with GoldenEye (1995) and Casino Royale (2006), but a lot of this looks fuzzy and gloomy (the over-dark 3D version should be strenuously avoided).
