I watched quite a bit of it actually, because I liked the spectacle of it, the CGI effects and most certainly the excellent theme tune.
But then I got turned off by some of childish notions of these inter-connecting lands, the gratuitous violence seemingly just for the shock value, and the extent of the fantasy, (pet dragons etc)
It was like an X rated Harry Potter almost.
Then, 2 weeks ago I started watching again, the latest series. I even Sky-plussed the series.
Again I was mesmerised by the effects, but then my same old objections came to the fore again, so I cancelled it off.
