Agreed, the whole "every episode is a different genre" is tiresome. I think that would have been fine for just one season, with some reason for that season to be like that. The show feels inconsistent and discontinuous, which is generally not what people like to experience. A good show may have both good episodes and sucky episodes, but still stand as at least the sum of its whole, if not more than its sum. SNW is kind of the opposite, where even if you have good individual episodes (and they're not all good), the whole does not stand together.
I do appreciate the experiment in television and story telling (one of the reasons I loved Fringe way back when, even when the "science" was pretty awful), but I think they should have learned earlier. Oh well, too late now.
I just realised there are whole adults young enough to not know what 80s hair looked like. đź§“
