The most interesting thing I took away from this soporifically sentimental movie was that Rin Tin Tin, before he hooked up with Rusty and the lieutenant way out there at Fort Apache, played canines other than himself. As for entertaining, exciting or touching elements to take away, there were none. Unless, of course, you want to give a mournful shout out to the great character actor, Joseph Calleia, and note the sad fate of a guy who could have been Anthony Quinn if only he'd been a bit taller. Otherwise, prepared to be bored as hell, especially in the scenes without Rinny, Jackie and Joe. Give it a C.
