Tyrrell – sorry, I lost track of this thread for a while. Also, I’ve been unnecessarily harsh towards people who leapt to the “aliens” conclusion when they were watching Signs.
My point is this: if we were presented, in real life, with the series of observed phenomena seen in Signs (crop circles inexplicably appearing in vast numbers, half-seen figures, bright objects suspended over cities, etc.) it would be unreasonable to pick extraterrestrial visitors as the most likely explanation.
However, people watching Signs tend to make that very assumption, because of a pop-culture context that includes movies. Apparently Shyamalan himself has said that they’re aliens, so that’s that (except for the aforementioned ambiguity in the word “alien” itself). However, that’s knowledge not communicated by the film itself. The information we do have is so ambiguous and sketchy that, first, there’s no logical basis for assuming they’re aliens except for prior experience with movies, and second, if we do assume they’re aliens, it’s the very lack of detailed information that makes their actions merely inexplicable rather than intrinsically implausible.
This is why I’d like to corner Shyamalan and see if he had any backstory for the aliens in his mind, even if it wasn’t presented in the film. As I said, a semi-competent science fiction writer (yours truly) could come up with explanations for all the odd goings-on; it’s just not necessary to the story.
As somebody said, Shyamalan seems to be, in all his movies, using a unique combination of a B-movie plot with A-movie characterization: believable human beings trying to deal with the possibly absurd reality with which they’re presented. (The current movie The Village, discussed at great length in Cafe Society, goes beyond the B-movie to use a “twist” that could have come straight out of a Twilight Zone episode.)
It’s an interesting technique, and so far it works for me, but I’d like to see him collaborate with somebody who could give him a really smart, original plot to work with.
