Netflix's hot streak of hit original series has continued this summer, but the streamer is even more fortunate with its acquired shows. Case in point, the drama Sullivan's Crossing has hit No. 1 on Netflix and become a bigger streaming hit than it is on The CW. The Waterfront has also proven to be one of Netflix's most popular shows, and we'd be surprised if it doesn't get a second season. Ditto Untamed, yet another mystery show subscribers can't get enough of this summer. You find these series and more among the must-watch drama shows on Netflix right now.
