Things I enjoyed about that episode: Nagato is adorable. There were tons of stupid faces. Some Christmas directions continue to be up in the club, which will be a good element.
Things I did not enjoy: everything else.
The play dialed back down putting us back. There was a silly scene together with the whole cast by way of a stairway (featuring Mikuru slamming boobs-first into Kyon as well as a lot of stupid faces), there was another one in a hall (featuring some "funny" mistakes and, you guessed it, stupid faces), and then there two more rear in the club room. Minutes passed. Jokes closed.
I counted a total of four hackneyed walkin gags that were mistake . The first one basically formed the foundation of the second scene of the episode, and was the longest. In a flashback that was foreseeable and overlong, Tsuruya described Kyon and Mikuru had bumped into each other and resulted in a mistake when Tsuruya walked in on them before. This mistake that was past promptly resulted in the present in a fresh mistake with Nagato, so if we are counting that as two, the total soars up to five, I think.
