I watched this particular episode because I had forgotten some of what had happened in the first 10 episodes of season 1. (This is why I tend to like watching season after they end.)
It summed up nicely the most important events, characters, and flashforwards, bringing you up to speed, but there was too much tell instead of show; it was like a list someone created, then completed it with the right scenes, adding some dialogue to bind it all together.
A bit boring in a way, and definitely a waste of time if you've recently watched the last 10 episodes. If not, however, this is a good way to refresh your memory.
