Cars made $461 million worldwide, sold more than 15 million copies on video and, mostly important, has moved more than a billion dollars in merchandise. I know the internet hates the movie (for reasons that I can't understand) but clearly millions of children loved it.
My reason for hating it is it doesn't make any sense! They're cars! They have no arms! How the hell do they maintain themselves?!?! It's "Maximum Overdrive" made more retarded! "Finding Nemo" works because despite being fish, they mostly behave as fish, and the toys of "Toy Story" behave like toys and the bugs of "A Bugs Life" behave like bugs, all in the worlds the movie created. The cars of "Cars" though don't have thumbs or arms, they can't function as anything other then cars, AND THEY DON'T BEHAVE LIKE CARS! They have houses? How? No arms means no building! The world would fall a part! How the hell did all those cars get into that car stadium?? You can't park cars on top of cars like that!! It's never acknowledged! CHRIST I HATE THIS MOVIE! And I'm clearly miserable and intolerant to certain things in movies!
Also, sales aside, children should NEVER BE TRUSTED! See Justine Bieber, Twilight, The Wiggles, and the continued ability of Eddie Murphy to get kids movies made for ample examples that success with children should never be the gauge of creating art! NEVER EVER EVER NEVER!
