Great episode.
Glad they didn't change scene to some other people. it would have been so anticlimatic.
Still, i think they struggled to pull it off.
Battle was big and bad, but I could see they expected it to be epic, but couldn't quite make it so.
Also, felt the insta-glib could have been actually more graphic if cuts were less that. I mean a brutal cut that didn't actually slice a man completely in half or a hack to the leg that simply cut half-way through would better represent, IMO.
I actually had tears in my ears from the music and unfolding action. I really never knew I had emotional stock in the characters, especially Tyrion, until now.
