I started it a few years back, then gave up after a couple of episodes. Came back to it again about a year later and watched it all the way through. I found the first 2 seasons difficult, but from Season 3 onwards I started to enjoy it more. Particularly from big events like the Red Wedding and the death of Joffrey - this is where the series started to get more exciting IMO. Seasons 4 through 6 were consistent, then 7 was the best season IMO because it set the stakes so high. But I agree that Season 8 didn't do justice to all the plot points they had been building to for years. It was too short, underwhelming and had a controversial ending that I didn't agree with. Could have been much better but for those few seasons in the middle it's worth a watch once. I'm not that much of a fan that I would watch it again in higher resolution - I'm happy to wait for the LOTR series that Amazon are developing and follow that instead.
