The 2010 Movie of the anime: "The Melancholy of Suzumiya Haruhi".
A new world is born where there's no more S.O.S. Brigade, and no one remembers it. Kyon tries desperatly to understand what happened to all is friends and why everyone doesn't remember anything. In the process, Kyon tries to make everything go back to what it used to be, unfortunatly, heยดs not the only one aware of this "new world".
the movie had quite an awesome plot in comparison to the series as it is not revovled around haruhi as much as she does not even get much of the film time but i found it quite good as the movie links to the series which requires you to watch the series to understand some of the jokes but it is still good movie regardless if you have seen the series or not
