I watched the season 1. That the show is horrible is an objective fact not in dispute. No one likes Game of Thrones. What people like is the idea of it. They like the idea of a show set in a medieval fantasy world that is more complex and adult than Lord of the Rings. They like the idea of rich characters, byzantine intrigues, and stunning plot twists. The success of the show rests entirely on its ability to give you the impression that it delivered on all those things without actually delivering on any of them.
