I thought it was a very solid episode. The water-dancing scene felt perfect, and I loved finally getting to see more of the Wall. Having read the first two books so far, the plotline with Jon, the Wall, and the Night's Watch is probably my overall favourite, with Arya a close second.
One minor quibble would be the scene with Jon and Tyrion on the Wall at night. In the book, that bit is very foreboding, but I didn't get anywhere near the same sense from the show.
