It is said that there are only 7 plots. Man vs nature, man vs. man, man vs. environment, man vs. machines / technology, man vs. self, and man vs. god or religion.
Another way of looking at plot is quest, voyage and return, comedy, tragedy, rebirth, rags to riches or poor to rich, and defeating a monster / monsters.
All these plots and themes can be included in a story. Lord of the Rings, for instance, is a quest above all else, as well as a voyage and return, with comedy, lots of tragedy, rebirth for Gandolf, Golum (sp?) Frodo and other characters, and it follows the man vs. man, man vs. machines (since Tolkien considered technology and magic I think one and the same in the case of the bad guys), man vs. self, and even man vs. god if you consider Sauron a god who demands to be worshiped by his slaves and followers. In Rocky, it is primarily man vs. man, and man vs. himself. In Little Red Riding Hood, it is man vs. nature, as was that movie about the soccer team who had to engage in cannibalism to survive a plane crash in the Andes. Bla bla bla.
I guess in the end, if it entertains you, a movie is a success. Sounds like a bunch of you really liked this thing.
