HBO & the media definitely promote him as the lead character/actor for Season 1 probably because Sean Bean (along with Lena Headey) is the biggest, most recognizable actor on the show, at least to an american audience.
I agree with that, but in regards to the actual reality of the story and show, there isn't a main character, which I think is the best thing about the show tbh.
