Ratatouille is a pretty game and manages to capture the style and personality of the movie rather well. Remy looks good and moves even better. Although the level design is varied and generally pretty good, it suffers from blurry textures and other little things. While I could easily write these off as being due to the system's hardware limitations, the Wii is capable of much more. These flaws are offset by better than usual special effects, such as bloom lighting, excellent particle effects and a neat motion blur that kicks in while running. Animation is generally good as well. The standard animations are fluid, but the best parts are the extra ones, like Remy coming to a sliding, skidding halt after running.
I still haven't seen the movie, so I'm not sure if the same actors from the movie reprise their roles in the game (to be honest, I couldn't tell you who is doing the voices in the movie). Whether the original actors do the voices or not, it is handled really well and entertaining - so either way it works. Music keeps with the mood of the game and mixes fun music with a bit of French flair.
