It will hold their attention.
I popped the screeners of this show on while I was working, just to get a little taste of it before watching it at home, and before I realized it, I'd watched an entire episode without doing so much as 30 seconds of work (sorry, boss). It's such a well-done series and its compelling storylines really hold your attention. Your youngest kiddos might not be as wholeheartedly enthralled, but for kids who are old enough to grasp the goings-on of the episodes, they'll be hooked. If you can pull yourself away from the screen (I'm telling you, it's hard), you might be able to sneak in a little me time while they watch.
