I got caught up with the episode last night, managing to avoid nearly all spoilers.
I really liked it. Yes, the breakneck pace continues, and the "deus ex machina" moment where the dragons showed up felt very much like the eagle taxi service from LOTR (which I was ok with too btw), but overall a hugely enjoyable episode.
I loved the way the Hound impaled their prisoner on a dragon barb to stop him getting away.
The production values on this show and especially this season are incredibly good - the CGI is pretty much movie quality.
Littlefinger's plan to drive a wedge betwen Arya and Sansa seems to be working. Though, I wasn't sure why he would suggest that Brienne could be useful, if Sansa was going to immediately send her away to King's Landing to represent her. Not sure what's happening there..
I try to stay away from all the other GoT fan sites out there, so I'm not aware of the current fan theories and all that, but has anyone considered the possibility that Daenerys might die in this next episode, or before the end of the show, leaving Jon as the only remaining Targaryen and rightful heir to the throne (once his parentage is established)?
