Oh, man. Not sure why you'd resist (aside from not wanting to follow the herd but really GoT is kind of special despite its mainstream popularity). It really is top shelf from all perspectives.
Bonus: It's pretty nuts first time through and so complex it's hard to follow (but still awesome) so it is one of those shows you can watch a few times all the way through and still pluck out nuances/dimensions you may have missed the first couple times.
I'm a little surprised they've managed to keep it going due to what must be an INSANE budget (which is what killed the series Rome) but I guess they're making enough money to push forward.
Enjoy. It's a great show.
