i watched it, it was pretty awesome, i specially liked their character development both for the movie, and the improvements for SAO. The story was pretty good i'd rate it maybe 8.5/10 it had some problems but, compared to what we've saw so far it wasn't bad at all,about hte character development maybe 8/10 since there where somethings they could've done better.
The Animation well... it was great(specially during the fights, it was pretty solid) 9.5/10 it was probably what made the movie gain life, the whole movie would be a 9/10 based on what i said before, but it really gives you some hype for the next season, since they did a great job with the movie, i think we can expect some great animations(better than the one they had before) for the next season, so yeah i'm pretty hyped for SAO 3 :D
