I really like it a lot.
In the opposite to blanka, I find that the story is really great, with a large range of game.
It's smart to not only have a continuous catalog of old school character,
But show a kind of gameplay instead with a real nice story.
For me, it's one of the best movie from last year. It's not surprising to see Lasseter in the credits.
This could be a pixar movie and is by far superior to "brave", even if the later had an oscar as reward.
Watch it, you won't regret.
