Maybe I'm not the only one who feels this way?
Although I still enjoy the show.....If I had to use one word to describe the season thus far it'd be 'underwhelmed'. I think GOT's has created such an expectation for themselves that they are entering an era of not being able to live up to it. The acting is still spot on....the production.....it's all great, but the content of the episodes IMO has been inferior to previous seasons to this point. Saying all of that I still think it's one of the better shows available to watch, and again....I still enjoy it greatly. It just seems like somethings 'off' this season and I can't quite pin point it.
To be fair, I'd say these first 5 epsiodes of Season 5 have had a somewhat similar role as the first 5 episodes of season 1. A lot of plotlines had their climax during the end of season 4 and those new plotlines need some time to get moving. A few examples (some minor book spoilers below, as in differences between books and show, but nothing that would spoil the show for non-readers):
Tyrion - we've always seen him scheming in King's landing, and he is no longer there, interacting with chraracters he doesn't know that well and just heading towards a new plot (despite that, I really enjoyed the Tyrion bits this season, especially in Episode 5).
Dany - Well, after taking Meereen, she really hasn't been up to anything totally exciting, but she has to learn to rule. Which is not that exciting to watch, but stilll necessary (and I liked most of her parts as well).
Jaime - on his way to a new quest, but just at the very beginning of it. Also very exciting for book readers, since he does something enirely different in the books.
Jon - We've had 3, almost 4 seasons build up for the battle at the end of last season, they are still trying to recover from that and deal with the consequences.
Arya - Everyone she's travelled with is either dead or thought dead, and she is in a completely new place.
and so on.
And of course, compared to the books after Book 3 (which is basically at the end of season 4), the show is still moving at lightspeed. I think they are doing a really good job of adapting the gist of those books to the screen without doing many of the mistakes the book did and becoming overly complicated. I'm pretty sure we'll get a few GOT-legendary moments this season, but in total this one is going to be more of an intermediate catch-your-breath and character development season, just like books 4 and 5 were. I'm pretty sure speed will pick up again at the end of season 5.
