I think theres a disconnect with the character because his hateful deeds are done off screen, so he doesnt have as big an impact as someone like Joffrey did. Yes, we dont like him. But we dont hate him either. Joffrey was a proper cnut, and his cnuty behaviour was given a very large spot light for Jack Gleeson to absolutely shine in. Aegon on the other hand, all we see are the results of what hes done. Couple this with the multitude of actors in the role, and it's a lot harder to get the same emotional response that Jack got in Thrones. We watched Joffrey killing Ros, and we fecking hated him for it. Not just the fact he did it, but how he did it. If they want the audience to have even half the reaction to Aegon that people had to Joffery, they are going to have to show us his cnuty behaviour in action.
