The show promises the battle for the throne amongst the most recent generation of kids and their parents but has done little to actually outline the definitive sides of that issue. Alicent was a great foil to Rhaenyra in the book but in the show they are to focused on putting both of them against the system in place rather than to actually create any interesting conflict between the two. Other than that, there isn't a ensemble cast that provides they're own individual ambitions and backstories into how/why they're interested in taking the throne. And the plot of Rhaenyra's affair has barley been explored which could've been used to accelerate the conflict between the houses but has been oddly been disregarded. The biggest issue of the show is that is tries to highlight and give importance to the characters of the show during the time period rather than the unspoken conflict of the "Game of Thrones."
