While I am still very concerned about the actual writing and tone of the film...I won't lie. They got the look down pretty damn well. This poster is filled with detail and color and life. It looks like Mario, but enough of its own thing to stand apart from the games without totally going in a different direction like the Sonic movies. The deviations in style (more realistic textures, making the Toads wear pants and have more visible legs, slight proportion tweaks and clothing changes here and there) all make sense for this being a big animated film. For a fan there's lots of cool references and nods, but even for someone who only kinda knows Mario, the bright whimsy is there and perfectly executed. Dare I say it...they nailed that aspect of the film so far.
Now the wait for the trailer...it's gonna be painful. Don't spoil me, folks - I'll be at work during the direct!!
EDIT: Also it's kinda wild to think this movie finally has a name. "The Super Mario Bros. Movie." Gets to the point. I dig it.
