After the revelations in “Good Intentions,” it seems things are aligned perfectly for catastrophe to strike. The events that occur in “Over the Mountain” may not all be dire, most are life altering, some even life stopping. Who knew Dewey Crowe (Damon Herriman) could pull off such a convincing bluff? He’s still a terrible shot but I never thought of Dewey as a killer. And since this season is supposedly about the Crowes, it is refreshing to see them take center stage in “Over the Mountain.”
