Black list the new lost

I can admit I watched a season or two of lost, and then got confused and left it never to return. I had multiple friends watch it all the way through only to be disappointed, and have no answers for me. Well I am in my own lost series.

It is called The Black list, I have been sucked in, and mostly because my wife watches them, but now I don't even know how we got to where we are. Why we are here, and why the main actor disappeared for a year. 1000's of people dead, millions of plots, and 8 years of no answers.
