Now I haven't seen the movie, but I have seen screen shots, and from what I've seen there, the DS version of Wall-e doesn't even compare graphically. I do realize that it is a handheld system, so it's not going to be movie quality graphics, but I have seen some absolutely beautiful games on the DS. Wall-E is not one of those games. The graphics are very simple, with a severe lack of detail. Wall-E himself is more or less a yellow cube. The worlds that they have available to play in are very plain, usually consisting of only one or two colors, and are just nondescript.
Unfortunately, the music isn't any better either. The one thing I liked was the cute little crunching sounds Wall-E makes when he creates a cube out of garbage. Other than that, nothing was worth noting, but at least it wasn't obnoxious either.
