One Piece 3D2Y is an hour+ long and it's called an episode. Same with the Episode of Nami, Episode of Luffy, and Episode of Marry. Same thing with Kara no Kyoukai. But hey! You may call them movies if you want to, but I'll stick with episodes.

And Livid, this might be random and all, but if you can, try to watch the .hack// series. Very similar to SAO (or maybe SAO is very similar to this, idk which aired first.) because it has the being trapped inside an MMORPG game theme
