It just seemed like it's trying (and failing) to re-live GoT's "glory days" a bit too much. Personally I rolled my eyes at several thi g due to how passé and try-hard they seemed, including the swearing, the whore house orgy scenes (really?) and that silly part where the tourney seemed to involve several instances of opponents just starting to hack each other to death (if real tournaments had been like that they would have run out of knights pretty quickly). I think it was also a mistake to remind us of the Song of Ice and Fire plot, especially considering the show made the dragons, Jon and Daenerys all completely irrelevant to the resolution of that plot.
On the plus side I think the production values seem *very* nice, in some ways even better than GoT. I suppose they can afford to make Kings La ding more lavish this time around, because it will be the sole/main centre of events, especially early on.
The actors also seem well cast.
But I'm just not feeling it. The early seasons of GoT had me hyped for the next episode, this...doesnt Right now I also feel that it doesn't have the same large cast of varied and interesting characters Got had.
Also we all know how this will end (the big strokes anyway) so part of the suspension is missing. Which is, of course, the trouble with prequels.
