Same here. I don't want to know what's going to happen, or feel the urge to compare the series to the books. "This scene went differently; he didn't say that; she should be taller," etc. That sort of thing gets in the way sometimes.
I did notice something on the first rewatch though. I'm wondering how the "deserter" from the prologue got south of the Wall without going back through the tunnel to Castle Black. I can't imagine he climbed over a 700 ft. tall ice wall.
