I was already watching the show before they introduced any LGBTQ characters. I'm not a huge fan of the show as a whole because I feel like it's trying to be darker and more serious, but it's often just cheesy. The acting isn't great, the dialogue is pretty silly, and they change so much from the source material that fans of the comics -- myself included -- feel alienated.
I do think they took things a step too far by making Penguin in love with the Riddler. I could actually see Riddler as being at least bisexual, but from everything I've ever known of Penguin, this just doesn't feel right.
Why don't you take a pill, bake a cake, go read the encyclopaedia.
