It's half Recap episode and half Music Video. It doesn't tell enough of the story to make any sense if you didn't already watch the original series, and if you did then the only reason to watch this is to just see a montage of clips from the show set to songs from the OST with Matsumoto talking to you. Don't get me wrong, It's not bad at all. It's exactly what it says it is. There's just not much reason to watch it unless you're really into this kind of thing.
