Note: I wrote this a couple of days ago. Posted in sequence with previous reaction posts, though. (I figured it might not make sense if I said I haven't had time to read right after posting another entry like this a few hours ago.)
Well, I haven't had a lot of time to read during the past few days but the thing that has stuck in my mind regarding A Dance with Dragons since my last reaction post was that George R.R. Martin should definitely be a candidate for the Bad Sex in Fiction award. I've read the scenes with Asha Greyjoy now, and they're pretty bad, but I think the absolute worst is the "entertainment" put on for Daenerys with the naked dancers who end their performance with simultaneous sex acts. There are some feats of acrobatics there that I just can't quite believe would ever work.
That aside, some stuff is finally happening (not with Daenerys, who isn't doing anything but refusing to open the fighting pits and worrying about her dragons in the dungeons and having internal monologues about her marriage prospects -- I can pretty much predict what every chapter beginning with her name is going to contain, before I start reading it). Tyrion's storyline is picking up, in unexpected ways at that. Tyrion's POV is probably the best one so far, if for no reason other than things are actually happening around him (though I don't know how much control he has over events). Jon Snow really isn't doing a whole lot (well, I guess Stannis has left and he's taken on some wildlings to help with defense of the Wall). Etc., etc.
