I didn't like this episode much. As a fan I can remember what's happened so far. I don't need to be reminded.
I can understand why the producers wanted a summary episode though. It's for people who are 'just tuning in' and don't have a clue what's happened so far. Now they're all caught up and excited to see the rest of the season. It is clever. Just not very interesting for the rest of us who are already fans.
Hopefully they won't do this too often; or more like ever again. I would rather see a re-run than a summary episode like this one. If they do really feel the need, well let them find a more creative way to give the summary.
