I finally finished Season 2 yesterday and didn't want to bump the thread, but now that it's already been bumped, I might as well give my thoughts.
I was initially into it and watching every Sunday, but started to lose interest halfway through and got behind, largely because I went on vacation, but I wasn't too eager to catch up even once I got back. I don't mind politics over action, but there was little scheming or power struggling. It felt like all parties just retreated to their camps and waited out the rest of the season. Daemon's plot was tedious to me and felt contrived to give him screen time and something to do. It felt like the writers wanted us to wonder if he was going against Rhaenyra, but I never really bought that, so it wasn't a surprise to me when it turned out that he wasn't. In general, that character was wasted this season, IMO. The dragon rider plot wasn't terribly interesting to me, either, partly because it was predictable. The season kept checking in on two characters who seemed to have nothing to do with the plot, and we didn't know a thing about any of other assembled nobodies, so it was obvious who the two rider-less dragons would go to.
The finale was rather disappointing. I agree with whoever it was that said that it would've been better to end with the first attack of the war. A notable character (like, say, Jace) could've died to end the season on a brutal note and declare "it's on." I guess that that would be a repeat of Season 1's finale, but it would've been better than ending with just mobilization. A couple of things also struck me as a little strange. The first was Daemon literally bending the knee. That seemed unnecessary (since when does a consort kneel before his/her spouse?) and out of character, especially considering that he stormed out of the room the last time that he saw Rhaenyra. I expected him to pledge his support, just not like that. The other was Rhaenyra and Alicent agreeing to "a son for a son" when Aegon and Aemond both dying will be two for one. It just seemed a little strange that neither of them addressed that.
Anyways, I'm only critical because Season 1 was so good and even the first half of Season 2 was good. The second half wasn't bad, just not up to the same level of what came before, IMO. It was still a lot better than the first two episodes of The Rings of Power Season 2, though, so nothing changed there. I still find HotD at its worst a lot more watchable than RoP.
