Most people who dislike the show base it on the first 2 episodes which are a grind, fairly boring and hella confusing.
After the rocky road,where the domino effect works with different story lines, the complexities of effects, dialogue, costuming and everything else is so ahead of its time and works together to make the most spectacular tv show I have ever seen.
Iv seen many people who claim to hate the show or who are hesitant to watch it suddenly change their minds and become enthusiasts. Some of my closest friends are ones who prdeached against the show, and are now the ones jumping on wikipedia after every episode learning everything regarding lore and conspiracy theories about characters.
You would be a fool not to atleast finish season 1, start now before you become like every single game of thrones viewer...
