This guy has been hit and miss with me so far. He can be REALLY great when given the chance. Other times......he's there. Not his fault though, he's just doing what he's told.
I will admit, he was still entertaining (not to mention intimidating) in Cold Eyes despite his lack of character development. Though, to be fair, no one had much development in that. As for The Good, The Bad, The Weird.....he's a stoic and he shoots things. That's it!! Compare that to his more colorful co-stars (especially Song Kang-ho).
