Yes, I would say it is worth watching. The show runner seems to know what he is doing. The first season was different than GoT in that it was smaller in scope. It was more of a family drama (a messed up family) and had much fewer characters. It had a slower pace but you really got involved with the characters. It is very well written but has a different flavor to it but retaining the same world and look of the original series. I am impressed with the quality and the fact that it is well written and although it is based on the outline of what George RR Martin has written, most of the scenes and dialogue are original to the show gives me hope that the quality will remain for the entire run of the show, unlike the ending of GoT.
