Iconic television programs often struggle to nail the ending. For every M*A*S*H, Newhart and Big Bang Theory (which absolutely stuck its landing last Thursday night), there is a Seinfeld, a How I Met your Mother or a Sopranos, that either tries to do too much, leaves too many head-scratching empty suggestions or just relies on a gimmick before fading to black. None of those shows was anywhere near as complex as Game of Thrones, and none of them approached the scope of its expansive cast or intricate story lines.
