I am in my 20s and am a huge fan of "Cars" and even I was sceptical that "Planes" would be a direct knock-off. It's not the same movie, has all different characters, and different settings. The good feelings associated with the movie are similar, but aren't all Disney animated movies about good feelings?! I really liked this movie for its animation. The flying sequences rival that of the scenery from "Avatar". It is definitely worth seeing it in 3D. I agree with some reviews that say that "Planes" is more aimed at children than adults, but that is okay. It is a Disney animated movie.....and a good one! Disney Animation did a wonderful job incorporating details of the scenery, plane history, and the US military, as well. I hope you enjoy it as much as I did!
