Been watching a lot of shows this summer but two of them really hit it off on my cool-list
Justified: About a U.S. Marshal in redneck county, great dialogs, great actors, good story, good shootin'.
Falling Skies: Produced by Spielberg, about a group of survivors of an alien invasion over earth. Good story, if you know The Walking Dead then it is a little like that, only the zombies have been traded for aliens.
