I'll be contrarian and say I really liked the episode. Sure, too many big names lived (as far as we can tell), but someone has to be around to lead the army of 1000 farmers wives and children against the Golden Company.

I really liked the battle scenes, even though I had no idea what was going on. The whole "fog of war" thing was pretty cool and probably pretty damn accurate, if you were to think about it. Was is the best choice for viewing? Absolutely not. But it put you into the frame of mind of the people in the battle, just blindly swinging your weapon and hoping to hit something. The only thing it was missing was more friendly fire.

Random thing that just came to me: The Lord of Light has no problem with lighting 10,000 Dothraki swords on fire, or an entire moat of defensements, or hell, bringing people back from the dead multiple times, but Melisandre couldn't be bothered to once walk up to Bran, say a couple magic words, and give him his legs back?
