I'm still hooked for now. Interesting that the son is in Mexico and he didn't even know it!
What I don't like is how this is too much like Vanished. With that show, there's the subplot of some wacko "helping" the lead FBI guy. This show also has some wacko who knows the lead character and he seems to be "helping" too, even though he's in prison.
Come on networks, show some originality!
