google the site "watch series" they stream TV shows, and are likely your best bet.
now, for my personal take on Game Of Thrones? Read the books on your iPad lol. They're much better. As a huge fan of them, despite loving some of the casting choices, I was, in the end, disappointed in the show. If you like the show, the books will blow you away!
Where do you live? I've also tried but either I can view it (I'm in Canada not USA) or I have to pay (which I don't want to do). If you're in the US and don't care about paying you can watch from their website. Also Itunes has them for download I believe. That's all I know lol
