Just like the last episodes this one was lacking what makes the series great that is, strong situations and strong characters
instead, most of what happens is a bit naive and uninspired, to say the least... they sent a few ships with food and this was enough to start a riot ? One could claim that this is not realistic and even if it was it should be set-up correctly... it should have been developed more...
the episode did not go any deeper into the lives of the protagonists... it did not follow anyone a bit closer or dug a little deeper... remember Tyrion Lanister, how he was always drunk, looked down on, always in brothels and taverns, meeting new people and getting into situations or adventures which he resolved his own way? Well, this character was phenomenal... the characters in S02 are shallow and uninspiring, taking up space than giving flavor to the outcome...
given the above one has to consider that GOT hadn't revealed its quality before the end of S01. But the expectations are high for House of the Dragon.
