I love this show so much. I have watched every episode multiple times. The cast is one of the best ever assembled. The basic premise is a team of FBI Agents who search for missing persons from fascinating cases. Not every episode is perfect but there are few that aren't very good. Part of the excitement is the search and there's always the anticipation as to whether they are okay or not. a WHY did they disappear? Where are they? Who is responsible? Are they okay now? The stories are well written and intriguing. You will quickly become hooked on this show once you start.
