Orphan Black
Orphan Black, would you consider it an LGBT show? The show features a gay male anda gay female character, a trans man and a possibly bisexual woman. It is worth noting that the characters sexualities are not really integral to the plot but just happens to be the characters orientation. Though an argument could be made that one of the relationships started by two women is integral to plot development it is not the fact that the relationship is between two women that is the main focus.
