Yeah, if you had maybe watched the first episode, rather than part of an episode part-way through a different season, you might've enjoyed it more, seeing as you'd actually be able to understand who everyone is and what's happening.
Your approach is like turning up half-way through a movie, playing on your phone for 5 minutes, leaving, and then saying the film was terrible.
You've not even given it a chance.
Also, consider reading the books. They're very good. Gives a good insight into things you might not pick up/understand in the TV series.
The TV series also doesn't follow the books 100% (especially from Season 3 onwards), so you're not just reading what you just saw and vice versa.
