Summer of the current year has opened the gates for three new 2016 dramas at CBS. After the first season of these drama shows, the network has decided to call it quits with "Brain Dead" and "American Gothic", according to the Hollywood Reporter.

This means that out of the three summer dramas, only the previously renewed "Zoo" will return on its second season.

"Brain Dead" stars Mary Elizabeth Winstead as a young Washington DC staffer who begins noticing something wrong with the politicians on Capitol Hill-mysterious bugs are eating their brains. The cast also includes Aaron Tveit, Tony Shalhoub, Nikki M. James, Johnny Ray Gill, Charlie Semine, and Jan Maxwell.

The launch of "Brain Dead" was with a massive marketing push and somehow debuted to just under 5 million live-same-day viewers in June and with its season finale episode with just half the viewership.

On the other hand, "American Gothic" starred Juliet Rylance and Justin Chatwin in a family drama. This summer drama debuted to only 3.4 million total viewers before its season finale episode. "American Gothic" was produced by CBS Television Studios and Amblin Television.

According to CBS president Glenn Geller, both "Brain Dead" and "American Gothic" missed to deliver what he was anticipating before the shows aired in CBS. However, Geller still remains committed to scripted in the summer and is still looking for ways to broaden the field with game shows that are similar to ABC's retro lineup.
