“Point Blank” (**1/2 out of four) was a fast-paced but uneven crime melodrama about a desperate nurse (Anthony Mackie) who teams up with an injured murder suspect (Frank Grillo) to expose rival criminals and renegade cops but all does not go as planned and the two are left in an isolated hospital to expose the villains, prove their innocence, and attempt to make it out alive. Film never quite hangs together but Mackie and Grillo’s usual strong performances and array of nonstop action may keep you entertained nonetheless.Marcia Gay Harden has a key supporting role as a cop.
