Bladerunner is definitely a case of this. They leave out key information, much of which you can eventually figure out,and some of which is a stretch for the audience to get, but it all would’ve helped enormously to let tyhe audience in on earlier in the film. Some of these facts:
1.) we’ve had a big war, and the effect has been to make life on earth worse. I believe in the novel, Earth is more radioactive; in the movie, it might be environmental – they don’t make it clear.
2.) One result has been to kill off lots of animal species. This is why the Voight-Kompff test makes such a big deal about killing animals or saving them, or possessing things made of leather – it’s a major crime to kill them, and probably not to sabve them if you can. It’s also why it’s assumed that the snake and the owl are animal replicants – artificial animals are more likely than real ones. And why the snake has serial numbers on its scales that can be traced.
3.) The environmental effects have screwed up California’s weather, which is why it always seems to be raining.
4.) California culture has turned even more polyglot, with a lot of Asian (the noodle bars, Geisha advertising imagery, street argor), although with other stuff (the street argot has German mixed in.)
5.) Because of the war, Earth is no longer the best environment for people either. In the novel, they wear protective clothing. In both novel and movie, people are encouraged to go to the offworld colonies , but the movie never makes this clear why. William Sanderson’s character failed the physical, which is why a talented guy is still on Earth.
6.) This may be opening a sore point, but when the film was released, Deckard wasn’t supposed to be a replicant. I dug out an interview with Ridley Scott from the time of the film’s release, and he explicitly says “We considered making Deckard a replicant…” which indicates to me that that isn’t the case. Reportedly, neither Ford nor Hauuer thought he was while they were filming, and hated the idea when it was later suggested. There was nothing suggesting it in contemporary reviews or writings. And it sure as hell isn’t the case in the novel.
7.) It really bugs me that Scott, in an interview, complained that “American audiences hate having introductory crawls” giving information. Not onlyt isn’t it true (What the hell starts every Star Wars movie?), but Scott even starts Bladerunner off with such a crawl. Which contains vital information (like what a replicant is), but leaves out pretty damned vital stuff (all of the above.)
The Big Sleep is legendary for being impenetrably confusing. Reportedly, many cast members couldn’t figure it out.
as for The Stepford Wives, it’s only the remake that’s confusing – the original is perfectly clear. The remaker looks as if it simply can’t make up it’s mind aboiut exactly what it wants to do, or be. It looks as if Frank Oz couldn’t resist the urge to use CGI to make several jokey scenes that weren’t consistent with the rest of the plot. Others on this Board have suggested it’s the fault of higher-ups at the studio. In any case, the the TSW remake is a visually gorgeous but mentally deficient guilty pleasure, that only works if you turn your brain off.
