THE WATCHERS ON THE WALL is another one of the famous "episode nines" of GAME OF THRONES, this time featuring a huge battle sequence from returning director Neil Marshall; a pity he didn't go on to direct more. This one features the long-awaited Wildling attack on Castle Black, and it's as good as you'd expect it to be, once you get over some mildly embarrassing extraneous sentimental stuff with Sam and Gilly. The last half an hour knuckles down to a breakneck, non-stop battle filled with all manner of gory incident and brutal deaths, with numerous long-running characters being bumped off and Kit Harington excelling in the action stakes. That 360 degree tracking shot is astounding and one of the best shots in the entire run of the series.
