Every movie is a "rip off" of something else. Ex avatar is pocahontas
every movie copies other movies,
but those two pics is like, more of a rip off, like clear. that monster movie from the 80s has almost the same basic plot, of course they changed everything, but if you describe the basic plot you could be talking about either movie:
"Kid meets monster they are not afraid of, becomes friends with them, and goes to the monster world, at the end the evil monster is defeated and the kid and the monster friend say goodbye" I dont know any other movie that is that close to monsters inc,
same with Cars and Doc hollywood, is the same exact story,
avatar IS Pocahontas in Space, you are just making my point right
