While it's quite good, unfortunately I think its a canning waiting to happen. The budget must be huge and at the pace it's going right now, it will catch up to where the books presently are in no time. Theres no real big time-skip in the books and those child actors aren't going to stay children forever. Honestly if I hadn't been a fan of the books prior I wouldn't bother watching.
Peter Dinklage, although way too handsome for this role :p, is the best actor in the entire cast. :D
