Story I rated an 8 since it really is not an addition to the main story it does touch on a few characters traits where you might have thought why does he do that, after watching you get that oh I see sort of feeling. The first episode was just funny to me. The other 3 touched on characters from other schools. Watch this if you liked the main story, you won't miss anything important if you head over to prince of tennis II.
Art I gave an 8 same art as original story.
Sound 8 leaves room for improving.
Character 9 I love all the different personalities in this anime.
Enjoyment 9 I rated the original anime a 10 this didn't have enough episodes to build excitement like the first series, these 4 are basically just add ons to the first 200 something episodes.
Overall I rate this a 9. If you enjoyed the first couple hundred episodes why not watch these for before going into Prince of Tennis II. Hope this was helpful.
