TRR: Try as he might, Sean Penn just doesn't have what it takes to be the next Liam Neeson. At least that's the conclusion you'll probably draw after watching The Gunman, the latest film from Taken director Pierre Morel. In it, Penn plays a reformed killer-for-hire who's only out to do good, but who inevitably gets pulled back into the world he thought he left behind years earlier. It's a thankless role that sees Penn's character beating up bad guys around the world, while trying to rekindle a romance with an old flame. But even though the film boasts some solid action sequences and an Oscar-caliber cast (including Javier Bardem, Mark Rylance, Ray Winstone and Idris Elba), it fails to rise above the level of mediocrity. Instead, it's merely serviceable, delivering the requisite amounts of blood, bullets and bone-bruising brawls, but nothing more. In a way, it's very similar to its Blu-ray release, which delivers excellent audio and video, but with precisely zero bonus features. Suckers for punishment will probably want to check this out, but everyone else should steer clear.
