Personally I liked this last episode. I am a politics/scheme/dialogue guy. Give me more Tyrion and Varys and I am good. The dragons and white walkers never did it for me.
Overall, the series fell short of expectations, IMO. It might crack the top 5 (more likely between 5-10), but before I started watching (before start of season 5, I believe), I was led to believe it was the best show ever. It isn't. But it is entertaining nonetheless.
Ever try to scroll through netflix to find a movie to watch? Spend 3 hours looking, then end up putting the regular season NBA game back on. GOT at least gets me to tune in every week. I will take it at face value.
