I finished re-watching House of the Dragon. I paid closer attention this time around. I still think this series is a far cry from season 1 of Game of Thrones, but I admit it was better watching it a second time than when I watched it when it first aired - though it is still boring at times.
There is one issue I can't get over though. Game of Thrones did not seem like a contrived story. At least for the first 4 seasons it appeared to have a plot that was being followed. Actually multiple plots for several of the main characters. HotD seems more contrived. The plot seems more about what the writers think will play well with the audience. Characters seem to flip and flop on who they are. Perhaps it is the jumps in time from episode to episode. The characters do not develop over time. Six years later they are just a bit different and we have to assume they evolved. HotD uses some what I will call epic scenes, particularly with dragons, while GoT often relied on the relationships between different characters to grab the viewers attention. There are not relationships in HotD like Arya and the Hound, for example. Or Tyrian and Varys. Or even Jamie Lannister and Brienne of Tarth. Some many compelling scenes were just two characters having a conversation.
Unlike GoT, picking out the real heroes in HotD is harder. There were a few ambiguous characters in GoT but all the characters in House seem to have more dark side than righteousness. Even the kids seem to be a bunch of brats. If there are characters with real honor and integrity, like Ned Stark or Jon Snow, they are not apparent in HotD.
I would give Game of Thrones a 9 of 10 for the first 4 seasons. It declined after that culminating with a rushed and awful final episode. Overall I still give it an 8 of 10.
House of the Dragon is at best a 6.5 out of 10, maybe a bit lower but I would not go higher. It tries to replicate GoT but falls short. The characters and the actors are just not as compelling. The story is not as compelling and the potential for a war with a bunch of dragons on both sides is not enough to make the story more interesting.
I still think a spinoff of the exploits of Arya Star would have been a lot more entertaining.
