Certainly. It's absolutely fantastic. Characters that I actually *like*, characters that I used to hate but now like, massive shocks (like the one two thirds through the way of "A Game Of Thrones", the first book, which I won't spoil), an interesting story where you don't know what will happen in the end (compared to a story like LotR where everything is set up right at the beginning and the only point of reading is to see how Sauron is stopped) and some really great quotes (After a guy's love has just died, when asked if he has anyone new)
"When the sun has set, no candle can replace it").
Sure, it gets a bit crude in places, but it reads far more like a historical novel than most fantasies with their bare-chested barbarians striking down hordes of enemies and chaste women in towers.
To call it the best fantasy series of all time is certainly no overstatement...
