I would agree that some more facial expression would be nice but isn't really a big deal though the game is moving so fast inless they do what SSB does that when you pause the game you can like zoom in and rotate around the characters to see the hit you got or something. And for guys like Big Daddy doesn't matter anyway. But it wouldn't hurt to have something more. As for the other stuff. I see what your saying but its more of a style preference then anything. Plus this isn't the completed game so we shall see what the actual one looks like
Not showing facial animation is hardly lazy. I think Parappa and Toro are the only characters who's faces you would ever see.
And I thought Parappa and Toro did have facial animation in my mind's eye, so I'm sure each other character does too.
