According to Dictionary.com the definition of trilogy is:
“a series or group of three plays, novels, operas, etc., that, although individually complete, are closely related in theme, sequence, or the like”
For the sake of this post/rant I’m going to claim movies as one of the etc. Within the last week I’ve seen the second movie in The Hobbit trilogy and The Hunger Games trilogy (yes, technically Hunger Games will be four movies but it’s based on three books). It amazed me the number of people after the movies said something such as “Seriously? That’s it? That isn’t a real ending, what happens next???” Presumably, you know that there was a movie one if you saw movie two. Also, I’m guessing if you are seeing movie two you know there is a movie three (maybe four). While movie-goers may not have read the books, the endings that leave you wanting more should not be a surprise. While Catching Fire left unresolved sub-plots, I think it was a good wrap up to a movie. With the Hobbit, you have a dragon flying off to destroy a city and the main character says, “What have we done?” To me, that is a fairly strong clue that, oh, the movie is over. I also heard this when the second LOTR movie was over.
Rant over. Have a good one!
