HEATHERS was a 1988 cult favorite that featured teen murder and suicide.. The remake not shelved was based on the film starring Winona Ryder and Christian Slater..
It was set to premiere in March, but was delayed after the Parkland, Fla., shooting in which 17 people were killed.
Viacom says the subject matter is not suitable in the current environment.
It is, however, open to the possibility of selling the show to a more fitting outlet.
