This nails the terrible military tactics on display:
Hollywood almost never gets it right, even movies like Saving Private Ryan, which I enjoyed thoroughly, and is well regarded can't do the true affect of high explosives on the screen. The blasts are so powerful you can feel them through walls and the like. Just using this as an example, of course, and it was well regarded in most regards.
Hollywood is all about the story, though, but even that has suffered without Martin. I am going to finish it out, but the quality diminishes a bit with each episode, that being said, it has for the most part been a good show and I have thoroughly enjoyed it but I liked the books a little better but isn't that almost always the case?
Books use their story plus your imagination and Hollywood has yet to trump that although, they are getting closer and closer.
