Like, none whatsoever.
The movie is basically just a recap of SAO with new animation.
The characters were never really OOC per se, but all the conversations felt a bit forced in some places. However, Suguha/Leafa got some development, as well as Asuna getting a new design which looked kinda cool, and a new world seen in ALO, but other than that nothing really happens until the last 15 minutes or so.
But, the same music from the show is used, so that's still good, and the animation looks as beautiful as ever.
Even if you're a fan of SAO and/or ALO.
I don't recommend it
