I like the art style of that game. For a movie license game it's nice to see they went and created an art style that would fit the DS and at the same time look unique and cute, instead of just using some standard cartoonized versions of the actors.
But it looks like this game is played with the stylus and there goes the fun out the window. -.-" Same as with the Zelda games... oh do I hate the stylus controls in games where the dPad would have been so much better.
