TV Guide reports that TNT has canceled The Great Escape -- the network's first foray into the reality genre -- after just one season. The show pulled sub-par viewing numbers relative to TNT's dramas, though its demo ratings weren't all that bad considering it was cheaper unscripted programming. It got just over a million viewers and a 0.5 A18-49 rating (though TNT sells advertising based on adults 25-54) in its season finale in late August. By comparison the scripted Falling Skies drew a 1.4 adults 18-49 rating and 3.8 million viewers that night before The Great Escape's season finale. In a very different competitive landscape this past Monday night TNT drama Major Crimes averaged a 0.7 rating with adults 18-49 but had more than 4.3 million viewers.
