When I started watching this show, it seemed amazingly simply. Throwback with a retro twist.
It was continuity-free TV. One fuzzy bear short of being Starsky and Hutch.
But slowly, they have woven more continuity and character into the show and have completely sucked me in.
This is in direct contrast to shows that slam you with a front-load of continuity right up front, letting you that they demand, DEMAND I say, a huge commitment from you.
In the case of shows like Lost and Warehouse 13, I appreciate this. It lets me watch them once and NEVER AGAIN.
