Dan Meth posted his Trilogy Meter and because I’m a pedant and a geek I thought I’d raise a little umbrage over a couple of points.

First off, a lot of these aren’t trilogies. Trilogies need to have a consistent narrative and at least some semblance of progressive story. If the next Batman movie isn’t by Christopher Nolan then those three movies put together are not a trilogy; at least, not necessarily. Back to the Future is a trilogy because the story is consistent throughout and each movie sets up the next. Going back to my point about films changing hands mid-trilogy belying the term, the X-Men films switch from Bryan Singer to Brett Ratner for the final film. But, and here’s where it gets tricky, they are still a trilogy because the second one sets up the Dark Phoenix storyline that the third one carries out, however poorly.

I honestly can’t say much about Rambo, because I haven’t seen any of them, but at the same time my intuition regarding Rambo is that the films merely follow the same character. Are any three consecutive Bond films a trilogy simply because the same character heads the film? I give the Die Hard movies a pass because the third one involved Hans Gruber’s brother, but it was different from the previous two in almost every other way. Similarly, I have trouble considering the Indiana Jones movies a trilogy; but there is a tenuous theme that runs throughout the movies regarding the growth and development of Indiana Jones that qualifies them, but I flip-flop on this subject.

We tend to have this desire to collect films into sets of three, even when they’re not a set of three. Which brings me to my biggest question about this chart. Which trilogy does it mean when it rates Planet of the Apes? Does it mean the first three Planet of the Apes movies? Because I don’t see how you could interpret those as a cohesive trilogy. The second one ends with the world being incinerated by a doomsday bomb. The third, fourth, and fifth movies are a wholy different animal and are in fact a consistent trilogy with an overarching storyline threading through the three films.

Not everything is a trilogy, but our pattern matching monkey-brains still have a fascination with the number three. The same circumstances don’t make movies a part of a trilogy. The same actors don’t make a movie a part of a trilogy. The same characters don’t make a movie a part of a trilogy. A consistent theme or ongoing story does. I know I’m being finicky about this, but people throw the term trilogy around for any set of three films and they’re not all trilogies.
