Hoarders does its second-season version of “Where are they now?” as it goes back to revisit what some previous hoarders featured on the show are now hoarding, or not hoarding, as the case may be. The problem with this is that, if the former hoarders have stopped hoarding, it’s good for them but boring for the viewer; if they haven’t stopped hoarding, it’s bad for them but also good TV. In short: this idea is basically lose/lose. (A&E, 9 p.m.)
