You can sympathise with Michael Keaton in the unenviable attempt to find a follow-up to Batman, but he blew it here.

Impossibly schmaltzy and of very dubious ethical value, the film casts Keaton as a cop whose partner gets killed, leaving Keaton and his wife with the dead man's three small daughters.

To avoid losing the girls, and to buy them a house, Keaton robs a drug dealer of his stake money.

Generally, the film lacks strength in most departments, and Keaton's supporting cast is weak by the standards of modern cinema.

Consequently, the film never whacks hard at the emotions, builds to a climax, or gives you the impression that it really knows where it's going. One Good Cop is one mediocre movie.
