Review:
If you haven't seen The Melancholy of Haruhi Suzumiya, stop reading this review and go watch that instead. Even just reading this review will ruin things about the original series for you, and it's difficult-to-impossible to follow along with this movie if you haven't seen the original series or aren't otherwise aware of the basics of this franchise.
Now that you've been warned, on to the synopsis. Haruhi has decided that everyone in the SOS Brigade will be celebrating Christmas together, cooking and eating an illegal hotpot meal in the club room, wearing costumes, etc. Kyon, as usual, is less than enthusiastic but doesn't even try to change Haruhi's mind, because he knows better - once she has an idea in her head, she's going to make it happen. And of course everyone else in the club just wants Haruhi to stay happy so that she doesn't accidentally remake or end the world with the godlike powers she doesn't even realize she has.
Then one morning Kyon wakes up as usual and goes to school as usual, only to find that a lot of people suddenly have colds. Even Haruhi seems to be affected, or so Kyon assumes, until he learns that Haruhi's seat now belongs to Asakura, the being who once tried to kill him. No one seems to remember who Haruhi is at all, and everyone who used to be unusual in some way is now normal or just plain gone. What happened? Who was responsible? Can Kyon get his old world back, and does he even want that?
