I can't say enough good things about this movie, but I have one complaint. And let me preface this by saying that maybe I can't hear as well as I used to; but the movie just isn't loud enough. It's clever, it packs a visual punch, I just want my ears to be punched a little harder. Come to think of it, maybe this is why I can't ear as well as I used to.
Side note: I'm also thoroughly enjoying the video game. It's got a very NES-y feel.
