"Double Bang" is a B-flick now buried in channel clutter on cable. The film has the usual cop flick ingredients including a good cop, a bad cop, a babe, some heavies, drugs, murder, yadayadayada. Although the story is nothing new, the flick dose manage to muster a kind of personality...a sort of likability as it doesn't take itself too seriously, doesn't always do what's expected, passes on opportunities to titillate, and the bad guy laughs all the way to the grave. An okay watch for channel surfers into crime flicks if expectations are kept within reason. (C)
