Be warned, it will bring back Endless Eight flashbacks - but in a good way. ;) If you survived the endless eight then this is a fun reworking of that story. It has a much bigger focus on the homework session which had some fun sequences - like the card game. Overall, if you have a soft spot for the series then this is a big warm hug. It doesn't add much to the series other than showing how comfortable the characters are with each other and they all get their own screen time with Haruhi, Kyon's sister and Asakura taking the lion's share. But with thestory being 'Endless Eight' it doesn't give you any new plot.
