Yes, I know, this is the week with a thousand shows commemorating Earth Day. But most of them weren’t finished in time for review, and the few that were ready weren’t worth comment. Besides, I’m too busy mourning the passing of Max Monroe: Loose Cannon. CBS brought it back for a three-week revival that ends Thursday (April 19, 9 P.M. ET). What can I say? I have a weakness for really bad action series. Actually, I’ll sit through just about anything…with one exception: Growing Pains. Lord knows, I’ve tried to give this simpy sitcom a chance. But it always strikes me as irretrievably dreary, plastic and stupid. As a matter of fact, the ABC tandem of Growing Pains and Head of the Class is one of the most barren hours on television.
