“Mercy” (*1/2 out of four) was a mercilessly dull melodrama about an older man (James Yaw) who goes through a series of personal crisises that lead to him mentally unravelling and falling back into alcohol abuse before an unexpected event brings him back from the brink. Yaw tries but his character is simply not all that compelling or interesting and neither is the movie, as it plods and never builds to anything dramatic. Yaw also wrote and co-produced.
